un-self-conficting python packages for non-default python

["Dr. Thomas Orgis" <thomas.orgis%uni-hamburg.de@localhost>]

Hi,

I carry some local patches that apply a common pattern to enable me
building the same set of packages with differing python versions. My
scripted builds have a selection of packages and a selection of python
versions, all py-foo packages being built with all respective
PYTHON_VERSION_REQD values.

I need to avoid installing unversioned files, except for the default
python version. The non-default builds might be not very useful (in
case the unversioned file in $PREFIX/bin is the whole point), but it's
nasty having to guess if a package using the py-foo scheme with
changing names depending on configured python version is actually
installable in parallel with differing pythons.

Anyhow … is this type of change acceptable in pkgsrc? Something obvious
that I should do instead?

Alrighty then,

PS: Yes, I'm trying to trim down my patches that were waiting too long
already to get committed … shortly before the freeze …
