installed python leaking into python 2.7.3 filenames

Hi,  

I'm having trouble upgrading Python from 2.7.2 to 2.7.3:

I've tracked down the .egg-info – it is being generated from 
Lib/distutils/command/install_egg_info.py which generates the filename from the 
version of python it is run from – and this is where the old (installed) python 
version (in my case, 2.7.2) has leaked in, so the file can't be found when 
creating the package because it has the wrong name. Notice the mismatch between

Writing 
/usr/obj/pkg/lang/python27/work/.destdir/usr/pkg/lib/python2.7/lib-dynload/Python-2.7.2-py2.7.egg-info
and
pkg_create: can't stat 
`/usr/obj/pkg/lang/python27/work/.destdir/usr/pkg/lib/python2.7/lib-dynload/Python-2.7.3-py2.7.egg-info'



It works fine in a jail / chroot.

I have no idea where and why this happens and how to fix it, so I'd be happy 
about any suggestion …

Cheers,
Matthias
