From Shane Bussman and my response:

Thanks for the info.  It appears that pyregion has added a new dependency 
on Pyrex or Cython.  I'll put this in the Python for Astronomers issue tracker 
so we won't forget to include this update.  BTW you might want to check into 
using Cython instead of Pyrex.  Generally speaking Cython is the preferred 
way to handle .pyx files since it is being very actively developed now.  Also, 
it looks like pyregion is supposed to build without Pyrex or Cython [1], but I 
guess that didn't work for you..
