[gdal-dev] Installation prefix for Python bindings on MacOSX ?

[William Kyngesburye]

I tried the bit there that gets the python path (get_python_lb), and it works to get the OS X user path if there is no arg, ie get_python_lib().

For OS X is that the python user path is independent of the installation prefix.

For the logic, one basic method in a makefile I can think of for detecting OS X is to check uname for Darwin.  Note that the python path is also independent on whether an OS X framework (MACOSX_FRAMEWORK) or unix library is built, so don't use MACOSX_FRAMEWORK to test for OS X.
