Chris:

I did use it at first, but decided that a simple pyrex wrapper was 
simpler and easier to maintain. 

My module is not really fully optimized to take advantage of numarray - 
it does the transformation one point at a time in a c-loop and stuffs 
the result in a list.  So, there's a lot of overhead in repeatedly 
calling the proj4 c-routine.  It would be a lot faster to recode the 
proj4 c-routine to process the whole array at once.
