See this thread for a detailed discussion of this topic:
  http://thread.gmane.org/gmane.comp.python.pyrex/3063

See this wiki page for some notes from David McNab on how
to address this issue:
  http://wiki.cython.org/PackageHierarchy
You might want to add comments there.

Like you, Arc, I would prefer that I could use one
set of file names that would work for both Pyrex and Cython.
I ended up creating a Makefile that can switch between
cython and pyrex and a small helper script to link the pyx
and pxd files under both naming conventions.

The Makefile passes into setup.py a parameter to tell it
which names and paths to use depending on the compiler.
Yes, it is a hack but it allows me to switch back and forth
for testing.  (The Makefile runs "python setup.py usecython"
from the parent directory to make this all work).
