Description Piotr Karbowski (RETIRED) gentoo-dev 2011-03-15 17:21:38 UTC 
Hi there,

media-libs/mesa failing if there is no libxml2 in system, as it running some python code inside. (Found it on new, clean install).

Reproducible: Always

Steps to Reproduce:
1. emerge mesa when there is no libxml2.
Comment 1 Rafał Mużyło 2011-03-15 18:18:25 UTC 
dev-libs/libxml2[python] is among RDEPEND.
Your system must be messed up somehow, if it doesn't work.
Comment 2 Piotr Karbowski (RETIRED) gentoo-dev 2011-03-15 18:32:15 UTC 
It is 100% clean gentoo install, fresh, I will reopen it and reproduce in chroot tomorrow.
Comment 3 Piotr Karbowski (RETIRED) gentoo-dev 2011-03-15 18:34:07 UTC 
Ah, you see, you are wrong, RDEPEND is RUNETIME DEPEND, it should be in DEPEND variable then.

Please add your emerge --info as a comment and the complete build log as an attachment to this bug report.

Honestly, even though it does seem as if DEPEND would be a better place for the dep, it seems unlikely it will change anything in your case.

You missed the following in the media-libs/mesa/mesa-7.9.2.ebuild
DEPEND="${RDEPEND}
Comment 7 Jeroen Roovers (RETIRED) gentoo-dev 2011-03-16 04:32:37 UTC 
It should all be correct. All media-libs/mesa ebuilds in the official tree correctly DEPEND on dev-libs/libxml2[python].

With no build log (the entire thing, if you are going to attach it to this bug report) showing an actual build error and no `emerge --info' as requested earlier, it's hard to see a bug here.

I had the same problem with mesa-7.10.1 in a hardened amd64 machine.

dev-libs/libxml2[python] is indeed in DEPEND="${RDEPEND}" so lets search further..

$ python
>>> import libxml2
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named libxml2

$ qlist -o libxml
(...)

$ eselect python list
Available Python interpreters:
