I'm OK with a GDAL-prefix install (with a small adjustment for the  
OSX framework if possible - a more explicit path, so that the python  
half of the path is ignored [$prefix/lib/python2.5/site-packages] and  
something like $prefix/Resources/python2.5 or $prefix/Libraries/ 
python2.5 is used instead).  Users would then either add that path to  
sys.path within python or scripts, or set it in PYTHON_PATH (or  
whatever it is) in the shell.

That would make it easier to support multiple versions, of both  
python and gdal-python, for application stability.

Seems to work on OSX.

As for any software that makes use of GDAL, gdal-python should only  
need the GDAL headers, and not all the extra headers for dependencies.

OSX encodes lib paths in libraries, so all it needs to directly link  
is libgdal.  I understand linux platforms may need the CFLAGS and  
link flags.

Nice features of OSX?  Or my own naivete?

For simplicity on OSX, I'm for supporting distutils.  Packagers (like  
me) and developers may be OK with an extra requirement, but others  
who want to go on their own might be put off by that.
