Going mad with python pygresql, where is postgres.h???

Please help me -

Where is postgres.h? I can't rebuild pygresql without it, but it's not
on my system. I'm running postgres 7.2.1 - which seems to be working
perfectly nicely without having a postgres.h in its include directory.

It seems to be a common problem. (PHP, pygresql installs are where I
find people asking about it in google, but I have not yet found a
solution.)  If I fudge it by untarring my pg distribution file, and
copying it from the src directory to my include, the pygresql build
still fails. Differently but still badly.

Has *anyone* succeeded with this? I'll happily go to private email to
send full details and post a resolution, but it is currently driving me
crazy.

BTW, I'm on mac OSX (a BSD variant, most unix things work out of the
box) and just upgraded to python 2.3

thanks
