Well, pkgsrc is an independent, portable sources-based packaging system which provides a complete set of packages for many architectures. Python is provided as a package per-se, and we do not yet have the ability to fallback to native python version.
If this patch is not to be pulled up to python 2.6 then we'll provide it as a separate patch to pkgsrc, that's really not a problem, i understand perfectly that python 2.6 is now on a maintenance state.

Thanks for your feedback.
