Bug#717512: pygobject: Build from source produces broken python3-gi not usable by python3.2

[Daniel Schepler]

Source: pygobject
Version: 3.8.3-1
Severity: serious

If I build pygobject from source, the resulting python3-gi package has no file 
/usr/lib/python3/dist-packages/gi/_gi.cpython-32mu.so, only _gi.cpython-33m.so 
(and similarly for _glib and _gobject).  As a result, if I try using the 
resulting packages to build e.g. python-distutils-extra, I get errors like:

(I originally saw this with a custom pbuilder setup "dogfooding" its own 
produced debs, but I've also reproduced the missing file issue using pbuilder 
with a vanilla chroot on amd64.)
