Hi there, Building x11-terms/gnome-terminal 3.2.0 from the gnome overlay without the python USE flag set on dev-libs/libxml2 results in a build failure for x11-terms/gnome-terminal. Adding the USE flag back fixes the problem. Reproducible: Always Steps to Reproduce: 1. echo 'dev-libs/libxml2 -python' >> /etc/portage/package.use/temp 2. emerge -1 dev-libs/libxml2 x11-terms/gnome-terminal Actual Results: if [ -f "C/gnome-terminal.xml" ]; then d="../"; else d="/var/tmp/portage/x11-terms/gnome-terminal-3.2.0/work/gnome-terminal-3.2.0/help/"; fi; \ mo="en_GB/en_GB.mo"; \ if [ -f "${mo}" ]; then mo="../${mo}"; else mo="/var/tmp/portage/x11-terms/gnome-terminal-3.2.0/work/gnome-terminal-3.2.0/help/${mo}"; fi; \ (cd en_GB/ && \ `which xml2po` -m docbook -e -t "${mo}" \ "${d}C/gnome-terminal.xml" > gnome-terminal.xml.tmp && \ cp gnome-terminal.xml.tmp gnome-terminal.xml && rm -f gnome-terminal.xml.tmp) Traceback (most recent call last): File "/usr/bin/xml2po-2.7", line 191, in <module> main(sys.argv[1:]) File "/usr/bin/xml2po-2.7", line 88, in main from xml2po import Main File "/usr/lib64/python2.7/site-packages/xml2po/__init__.py", line 27, in <module> import libxml2 ImportError: No module named libxml2 make[2]: *** [en_GB/gnome-terminal.xml] Error 1 make[2]: Leaving directory `/var/tmp/portage/x11-terms/gnome-terminal-3.2.0/work/gnome-terminal-3.2.0/help' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/var/tmp/portage/x11-terms/gnome-terminal-3.2.0/work/gnome-terminal-3.2.0' make: *** [all] Error 2 emake failed Expected Results: No build error.

gnome-terminal-3.2.0 has a build-time dependency on app-text/gnome-doc-utils. All versions of gnome-doc-utils have a build-time and run-time dependency on libxml2-2.6.12[python]. I suppose the thing to do is to make libxml2's python USE flag enabled by default, since gnome-doc-utils are used all over the place. This would have been caught simply by running emerge with the --deep argument. Which, incidentally, really ought to be made the default behavior...
How about enabling it in package.use of the gnome desktop profile? Doesn't sound like a good enough reason to enable it for everybody in the ebuild.
(In reply to comment #2) > Doesn't sound like a good enough reason to enable it for everybody in the > ebuild. Mesa also needs libxml2[python] to build. And even if you use closed-source drivers, mesa is still a required dependency for xorg-server.

Well, you must admit that you have a skewed view of the world through your GNOME goggles. On MY desktop: % equery d gnome-doc-utils * These packages depend on gnome-doc-utils: app-text/evince-2.32.0-r3 (>=app-text/gnome-doc-utils-0.3.2) gnome-extra/gcalctool-5.32.2 (>=app-text/gnome-doc-utils-0.3.2) media-gfx/gthumb-2.12.3 (app-text/gnome-doc-utils) x11-terms/gnome-terminal-2.32.1 (>=app-text/gnome-doc-utils-0.3.2) .. which hardly qualifies as "all over the place" > (In reply to comment #2) > Mesa also needs libxml2[python] to build. And even if you use closed-source > drivers, mesa is still a required dependency for xorg-server. In the mesa case, libxml2[python] is *ONLY* a build dep, so when you rebuild mesa then libxml2[python] will be rebuilt (as needed, if deps are not satisfied). So, let's throw the mesa case out and revisit comment #2

So, let's throw the mesa case out and revisit comment #2 libxml2[python] will not be rebuilt when you run "emerge mesa". Instead, you will get an error message, and you will need to edit /etc/portage/package.use (inconvenient) or enable --autounmask-write (dangerous). And if every person who has to build mesa would need to manually set a particular USE flag on libxm2, then Gentoo should, IMHO, set this use flag by default. PS. On the system where I am typing this: $ equery d gnome-doc-utils | wc -l 67

Points taken, but please be careful... "inconvenient" & "dangerous" are just opinions that will encourage bikeshedding. > PS. On the system where I am typing this: > $ equery d gnome-doc-utils | wc -l > 67 Well, it isn't about any *one* system here, I just included that info to point out that you cannot say "all over the place" [on every Gentoo desktop]. You just proved my point. So yes, on GNOME desktops gnome-doc-utils is used a large number of times. In the end, I think we have highlighted a optimal solution: echo "dev-libs/libxml2 python" >> .../profiles/targets/desktop/package.use all because xorg-server needs mesa and this solution is the least annoying for Gentoo users (and satisfies the most non-desktop users[1]) - What do you think? [1]: This is what you might see on a server, eg: % equery d libxml2 * These packages depend on libxml2: app-arch/libarchive-2.8.4-r1 (!expat ? dev-libs/libxml2) dev-lang/php-5.3.8 (simplexml ? >=dev-libs/libxml2-2.6.8) (soap ? >=dev-libs/libxml2-2.6.8) (wddx ? >=dev-libs/libxml2-2.6.8) (xml ? >=dev-libs/libxml2-2.6.8) (xmlrpc ? >=dev-libs/libxml2-2.6.8) (xmlreader ? >=dev-libs/libxml2-2.6.8) (xmlwriter ? >=dev-libs/libxml2-2.6.8) (xsl ? >=dev-libs/libxml2-2.6.8) dev-libs/libxslt-1.1.26-r1 (>=dev-libs/libxml2-2.6.27:2) net-analyzer/rrdtool-1.3.8 (>=dev-libs/libxml2-2.6.31) net-dns/bind-tools-9.7.3 (xml ? dev-libs/libxml2) net-libs/neon-0.29.6 (!expat ? dev-libs/libxml2) sys-devel/gettext-0.18.1.1-r1 (dev-libs/libxml2) www-servers/lighttpd-1.4.29-r3 (webdav ? dev-libs/libxml2) x11-libs/cairo-1.10.2-r1 (svg ? dev-libs/libxml2)
libxml2 has been in my hitlist for splitting out the bindings to a separate package for a while now. Something that has been for a very very very VERY rainy day for me though. How feasible would that be? Stuff needing python bindings just deps on it, gets around of portage not auto-including a reemerge with satisfying USE flag demands, etc etc. A clean split case in a perfect world (where there are no maintainer time problems)

I think that would be a reasonable solution.
update summary, please comment if you have an opinion @kde: You are a child of the desktop profile but I can't see why or how this would adversely affect you. Consider this an FYI.
