[Pyrex] [Mac Inter Core Duo OS 10.4.9 ] compiler complains about pyrex created .h

[David Goldsmith]

I googled Pyrex: "parse error before '(' token" and hit an archived 
SciPy post; the message following the relevant post - it was unclear 
whether it was next in thread, next in time, or both - suggested that 
the problem might be an out-dated Numeric.  Have you all updated to 
numpy, and if not, if I don't have Numeric, only numpy, could that be 
the (or will that be a) problem?
