Hey list
during yesterday's upgrade I read the news about python 3.4 being the
new profile default. In its course a lot of python-related packages were
indeed rebuilt (up until then I had set PYTHON_TARGETS to 2.7, 3.3 and
3.4 manually due to blender, which already required 3.4). But in the
end, depclean will still not remove python 3.3. So I dug and after some
more cleanup (some packages had to be un-keyword to support 3.4) I got:
---[ $ emerge -cpv python:3.3 ]-
Calculating dependencies... done!
dev-lang/python-3.3.5-r1 pulled in by:
dev-python/lxml-3.3.5 requires =dev-lang/python-3.3.2-r2:3.3
dev-python/setuptools-7.0 requires =dev-lang/python-3.3.2-r2:3.3
What I don't understand:
---[ $ emerge -pvuD --changed-use --with-bdeps=y world ]
[...]

The following keyword changes are necessary to proceed:
(see package.accept_keywords in the portage(5) man page for more details)

---[ $ eix -e lxml

If I upgrade the stable lxml 3.3.5 to the keyworded 3.4.1, this
problem will probably go away. But I want to understand it. How can I
find out why portage thinks I need lxml 3.4.1? 3.3.5 knows about python
just 3.4 as well, it only uses a different shell syntax to express it:
3.3.5: PYTHON_COMPAT=( python{2_7,3_{2,3,4}} )
3.4.1: PYTHON_COMPAT=( python{2_7,3_3,3_4} )
---[ $ emerge -pvc lxml ]---

Both inkscape and calibre only care about python 2.7.
Cheers and good night for now.
