Arch Linux

Description:
At the moment you can easily install any python lib that has support for python2 or python3 from the repositories (at least the ones that are added).Most of these have one shared PKGBUILD and build both python3 and python2.
pypy is only in the community repos, but adding pypy libs would only take a copy the package routine from python2 and a simple replace of python2 to pypy.There are some rare corner cases that don't work like this (numpy has it's own repo,matplotlib isn't a 100% compatible afaik and some packages that use too much cpython could need manual intervention), but the compatibility is great http://pypy.org/compat.html
Right now most people probably just use pip for pypy to install missing libs but having pypy lib alternatives in the official repo would be great.
Kind regards,
