I noticed that this generates a depedency like "|| (
=dev-lang/python-2.7* =dev-lang/python-2.6* )" which is very similar
to the way that QT3VERSIONS works in qt3.eclass. One thing that is
sub-optimal about these types of dependencies is that you end up
with lots of installed packages that have out-dated dependencies
when the next minor version of python is released (python-2.8 in
this case). In the case of the python dependencies, it might be more
optimal to use a version range like ">=dev-lang/python-2.6
<dev-lang/python-3".
