To answer my own question, it won't using %cython in the notebook, or
using sage.misc.cython, which is what the notebook calls. It can be
done by adding a module to sage; but this requires changes to sage
scripts.
The cython compiler extends distutils.build_ext and
distutils.extension to pre-process the .pyx file and build the c
file. The .pxd search path is specified in a separate argument
("pyrex_include_dirs") in the sub-classed Extension class. The
setup.py script for a .pyx is therefore materially different from the
one used in %cython.
With the right setup.py script in place I have successfully compiled
my test prog. I will probably modify sage.misc.cython.py to do the job
for me.
