Hello,

It has been committed, it's now possible to install python 2 and 3
interpreter without checking for which repository it has been compiled :-).

However there is bug in pkgng that does not allow to install a python 2
and python 3 module because it relies on the origin which is
devel/py-foo and not the port name py27-foo | py33-foo.

I've posted an issue on the FreeBSD pkgng github repository [1].

Also, know I would like to get in touch to the ruby team so they do the
exact wrapper of the ruby interpreters :-).
