You can use PYTHON_PATCH_SCRIPTS (lang/python/ in pkgsrc

It won't work as a binary package (except I want the Python version that
build machine uses, which might not be exactly the one). 

When installed, it doesn't allow me to change the version I choosed during
"compile" time (I must have pkgsrc installed).

So, I don't think it's worth to import that Makefile to pkgsrc. It doesn't
fix anything, really.

Such functionality (provide one, common name for one or more different
versions of single package) should be provided by some lower layer of
pkgsrc, in a generalised way, available for all packages.

Check Debian's "alternatives" system to see one of possible solutions.
