Bugzilla Bug 46824

metakit-2.4.9.2-r1 ebuild relies on python-config in src_install(), and on
python -c 'import sys; print sys.version[0:3]' in src_unpack(). This is
problematic, because the two methods are not guaranteed to return the same
python version.

Basically, /usr/bin/python is the latest version of python, while
/usr/bin/python-config is the last version of python that was installed (i.e.
emerge '<python-2.3' will clobber python-config). 

So, if you have emerged a python-2.2 after python-2.3, the metakit ebuild says

/bin/sh ./libtool --mode=install /bin/install -c Mk4py.so
/var/tmp/portage/metakit-2.4.9.2-r1/image//usr/lib/python2.3/site-packages
/bin/install -c Mk4py.so
/var/tmp/portage/metakit-2.4.9.2-r1/image//usr/lib/python2.3/site-packages
/bin/install: cannot create regular file
`/var/tmp/portage/metakit-2.4.9.2-r1/image//usr/lib/python2.3/site-packages':
No such file or directory
make: *** [install-python] Error 1

!!! ERROR: dev-db/metakit-2.4.9.2-r1 failed.
!!! Function src_install, Line 49, Exitcode 2
!!! (no error message)

Note that metakit-2.4.9.3-r2 performs some kind of ebuildical magic to avoid
this problem, but unfortunately, it's ~x86 at the moment.

Reproducible: Always
Steps to Reproduce:
1. emerge '<python-2.3'
2. emerge '=metakit-2.4.9.2-r1'


Actual Results:  
ebuild fails

Expected Results:  
ebuild succeeds...
