pygresql build/install problems: use setup.py?

[python 2.3a1 & 2.2, postgresql 7.3.2 & 7.2.1, x86 linux]

As you note from the above line, I'm wrangling multiple versions
of python and postgres[ql].  I use the PyGreSQL interface from the
postgres source dist.  But I need to install PyGreSQL for other
than the default python.  I know I could hack it by hand, but it
seems like there could be an optional arg to configure like:
 ./configure --with-python=python2.3

to specify a binary (and include files and lib install destination)
other than the default.  Maybe it needs a separate option:
 --python-include=/usr/local/include/python-2.3 

I'm hoping some autoconf wiz will take this in hand -- auto* stuff
scares me...

I succeeded by fixing up setup.py:

Isn't this the right thing to do?  It should use the .. lib and include
dirs if they exist, since these are sure to be correct, as opposed
to hard coded /usr/lib/pgsql and /usr/include/pgsql which might 
not exist until an install has been done, and worse, might be from
an older postgres version.

It seems like the makefiles should just run  $PYTHON setup.py build
and  $PYTHON setup.py install

since setup.py has a much better chance of installing in the right
directories, or am I missing something?
