pg.py under Mac OS X

Hello Interfaces List,

I am trying to get python access to postgresql-7.4.7 under Mac OS X
10.3.8. When I compiled postgresql from the source I used --with-python,
but got the following error:

*** Cannot build PL/Python because libpython is not a shared library.
*** You might have to rebuild your Python installation. Refer to
*** the documentation for details.

I figured I'd simply install PyGreSQL instead. I installed postgresql and
got it going then I dropped down the PyGreSQL-3.6.1 archive, untar'ed it
and ran:

python setup.py build

but got the following error:

gcc -fno-strict-aliasing -Wno-long-double -no-cpp-precomp -mno-fused-madd
-fno-common -dynamic -DNDEBUG -g -O3 -Wall -Wstrict-prototypes

pgmodule.c:316: error: `CASHOID' undeclared (first use in this function)
error: command 'gcc' failed with exit status 1

After a quick search on my system, I find that postgres.h only exists in
the postgresql-7.4.7 source directory, and was not installed with the
headers in /usr/local/pgsql/include/

Is this correct? Should I be approaching this a different way? I am unsure
of how to continue to get this going.

Any help would be great,

Cheers
