That's not the way you use pyrexc -- it's a shell
command, not a Python module.

There are two currently supported ways of invoking
pyrex:

1) Write a setup.py that imports and uses the distutils
    extension.

2) Write a Makefile that uses the pyrexc command, gcc,
    etc. to do it all the old-fashioned way.

You could also use pyrexc from the shell or a Makefile
to generate the .c files, and then use a normal setup.py
to compile and link them.

The Demos directory contains some example setup.py files
for you to look at.

It's also possible to import the Pyrex compiler from a
Python script and call it directly, but the details
aren't documented yet.
