Brian,

You could also take the modern Python route: simply build the library
--without-python, get the setuptools module by downloading and executing

http://peak.telecommunity.com/dist/ez_setup.py

and then execute:

  $ easy_install GDAL

Howard has put a ton of work into it. Should just plain work and build
numpy for you as well.

Cheers,
Sean
