Bugzilla Bug 192902

emerge vmd doesn't compile because there are issues with python. I guess it is
related to python-2.5 vs python2.4

Reproducible: Always

Steps to Reproduce:
1.emerge vmd
2.
3.

Actual Results:

Yeah, vmd won't compile with python-2.5. I reported it on the vmd mailing list,
but no solutions yet.

OK, so the problem is in PYVER in .ebuild
There is a partial implementation of PYTHON_OVERRIDE_PYVER variable which
doesn't work for VMD, ie I tryed:

PYTHON_OVERRIDE_PYVER="2.4" emerge vmd

and it doesn't work. However if I change the PYVER in the ebuild itself emerge
vmd works OK!

I guess I'll file a bug against eclass/python.eclass

If I understand vmd history file correctly they fixed the problem in their
development version :-)

Hm, that must be an amd64 specific "int thingy" since it compiles
just fine on my x86 boxes. Anyway, I'll post a possible fix below.
Please let me know if it works since I don't have an amd64 box
to test.

I think it is just python-2.5 issue. I made some more changes in order to
really fix the problem. Please check new attachments.

patch for vmd-1.8.6 to support python-2.5

Hi milan,

That looks good to me, thanks! I'll commit it to portage
tonight.

Best,
Markus

In cvs, thanks!
