[Gdal-dev] Python modules fail to compile on MAC OS X

[Zak James]

Jeroen,

I answered this question on the list a few months ago. You may find  
more details in the archive, but I'm including what I wrote then.

I've since determined that for install to proceed, you need to set a  
pymod install directory in GDALmake.opt:
INST_PYMOD      = ${prefix}/lib/python2.3/site-packages/

and make some modifications to the pymod makefile because it thinks the  
bundle extension will be .dylib instead of .so
