Thank you. It worked. 

Just one thought though. Would it be useful if Pyrex provided some way to directly declare an extension
subtype from a PyType_Type instance declared in another C file? If one needs full control of memory
management for example, one would write a base type in C, then use Pyrex to create the extension 
module boiler plate and any subtypes. The Pyrex output file would be linked with the C base type file
to make the final extension module.
