Never try to use a C file produced by Pyrex if the Pyrex
compiler reports an error. Your .pyx file gives me:

/home/cosc/staff/research/greg/tmp/foo.pyx:21:24: Cannot convert Python object to 'TidyDoc'

You seem to be somehow expecting Pyrex code to pass
in a TidyDoc, which is impossible because it's a
C struct. You'll have to wrap it in an extension
type.

Have you studied the Quick Guide to Pyrex?
