[AstroPy] package requirements for pyregion

[Jae-Joon Lee]

This is a known issue.

 https://github.com/leejjoon/pyregion/issues/10

And as far as I can see this is a bug in setuptools, which seems to be
fixed recently.

 https://bitbucket.org/tarek/distribute/issue/195/cython-build_ext-support-broken-when-using

A workaround has been implemented in the dev. branch of pyregion.

 https://github.com/leejjoon/pyregion/commit/ff785c85464d4ef912931037beca8c47c7674e53

And yes, pyregion should build okay if you don't have Pyrex or Cython.
The problem only happens when you have Cython but not pyrex.
