There are a number of weird things going on here: - why does libary_consumers have a "lib" entry? lib /Library/Gentoo/usr/lib/postgresql/autoinc.so,/Library/Gentoo/usr/lib/... but: % scanelf -n /Library/Gentoo/usr/lib/postgresql/autoinc.so TYPE NEEDED FILE XET_DYN /Library/Gentoo/usr/lib/postgresql/autoinc.so - where does "lib" come from? to end up in preserved_libs, it needs to be in old_libs: old_contents = self._installed_instance.getcontents().keys() old_libs = set([os.path.basename(x) for x in old_contents]).intersection(libmap) but, there is no "lib" file in emacs: % qlist emacs | grep lib /Library/Gentoo/usr/share/emacs/22.1/etc/celibacy.1 /Library/Gentoo/usr/share/emacs/22.1/lisp/calendar/diary-lib.el /Library/Gentoo/usr/share/emacs/22.1/lisp/calendar/diary-lib.elc /Library/Gentoo/usr/libexec/emacs/22.1/i386-pc-solaris2.10/sorted-doc /Library/Gentoo/usr/libexec/emacs/22.1/i386-pc-solaris2.10/digest-doc /Library/Gentoo/usr/libexec/emacs/22.1/i386-pc-solaris2.10/hexl /Library/Gentoo/usr/libexec/emacs/22.1/i386-pc-solaris2.10/cvtmail /Library/Gentoo/usr/libexec/emacs/22.1/i386-pc-solaris2.10/vcdiff /Library/Gentoo/usr/libexec/emacs/22.1/i386-pc-solaris2.10/update-game-score /Library/Gentoo/usr/libexec/emacs/22.1/i386-pc-solaris2.10/fakemail /Library/Gentoo/usr/libexec/emacs/22.1/i386-pc-solaris2.10/movemail /Library/Gentoo/usr/libexec/emacs/22.1/i386-pc-solaris2.10/rcs2log /Library/Gentoo/usr/libexec/emacs/22.1/i386-pc-solaris2.10/profile /Library/Gentoo/var/lib/games/emacs/.keep_app-editors_emacs-22 - because "lib" has external consumers (weirdness in the library_consumers file) the dir is not removed, eventually shutil dies. Should the code be more defensive, or is the library_consumers file supposed to be 100% correct? Note that I had to patch a bit there, because it only works for ELF/Linux. See also commits 9497-9499: http://sources.gentoo.org/viewcvs.py/portage/main/branches/prefix/pym/portage/dbapi/vartree.py?rev=9499&view=log (I'm filing a bug, because this is genone's stuff, who is hard to catch in IRC, obviously, I'm using Prefix Portage.)
Created attachment 147575 [details, diff] fixing the wrong NEEDED entries by reading scanelf's output correctly Ok, the bug is caused by a wrong NEEDED file: % grep earthdistance.so $EPREFIX/var/db/pkg/dev-db/postgresql-8.2.7/NEEDED /Library/Gentoo/usr/lib/postgresql/earthdistance.so /Library/Gentoo/usr/lib/postgresql/earthdistance.so:/Library/Gentoo/usr/i386-pc-solaris2.10/lib:/Library/Gentoo/usr/i386-pc-solaris2.10/lib/gcc:/Library/Gentoo/usr/lib:/Library/Gentoo/lib This is caused by bin/misc-functions.sh around line 160. The scanelf command returns: % scanelf -qyRF '%p:%r %n' /Library/Gentoo/usr/lib/postgresql/earthdistance.so /Library/Gentoo/usr/lib/postgresql/earthdistance.so:/Library/Gentoo/usr/i386-pc-solaris2.10/lib:/Library/Gentoo/usr/i386-pc-solaris2.10/lib/gcc:/Library/Gentoo/usr/lib:/Library/Gentoo/lib That is: the filename, the runpath, a space, and nothing (there are no deps) The code in bin/misc-functions.sh fails to parse it, since it uses default IFS, so the trailing space is removed by bash, making sure that the loop that handles it doesn't see the space, and hence considers the runpath as needed lib, and hence "lib" shows up as required lib. I fixed this in the attached patch, but this is SpanKY's territory, IMO. While I was at it, I also noted that rpath is wrongly extracted from ${l}, if you have more than one path stored in it, rpath only contains the last one. If you are unfortunately enough to have spaces in your paths, you even will end up with an incomplete rpath. I applied the patch to prefix in r9582 as it fixes the problem for me.
I had the same problem on OS X 10.5.2, using portage-2.2.00.9583, when emerging Python: dev-lang/python-2.5.1-r5 USE="doc ncurses readline ssl tk -berkdb -bootstrap -build -examples -gdbm -ipv6 -nothreads -sqlite -ucs2" Using FEATURES="-preserve-libs" solved the problem.
fixed in prefix.
