Hi Vicky,

Thanks for the feedback.  This was already reported and being tracked
[1], but we'll get on it.  As mentioned in the issue, the dependency
can be met with Cython and that is probably a better option at this
point.   Also, it looks like pyregion is supposed to build without
Pyrex or Cython [2], but this doesn't seem to work and may be a
pyregion issue.
