[Cython] cimport inside a package

[Robert Bradshaw]

I think the problem is that it's getting confused between the names  
"foo" and "zap.foo." I'm not sure, however, what the correct solution  
to this is, other than giving the names via setup.py, but perhaps  
someone more familiar with distutils and/or compiling extensions by  
hand would have a better idea what's going on.
