We can also just package the .c file built by Pyrex whenever the 
developer changes the .pyx file. That way, there is no further 
infrastructure to include. On the other hand, as Darren suggested later, 
one can do what setuptools' build_ext command does without setuptools 
(if an extension source ends in .pyx, call pyrexc on it. If pyrexc is 
not available, skip that step. In both cases, then compile the .c file 
with the c compiler.) Darren, if you're still having trouble with this, 
I can dig up the old code I had that did this (I switched to setuptools 
for this, and other stuff, a long time ago).
