I should have left my problem to be cured by a night's sleep, sorry.
Thanks for your help, anyway.

I missed that because my Makefile seems to be continuing despite pyrex
failing.  I guess that's a distutils problem...

Actually it's a pointer (and I messed up the Pyrex declaration of it).  I
was expecting SWIG-like handling of pointers, but now I understand you use
extension types for that, which seem very nice!  Having fixed that, all
seems to be working so far.
