[gdal-dev] Python Bindings

[William Kyngesburye]

I couldn't think of anything at first, but now I wonder if it's an arch problem.  Usually errors say if there is a missing architecture in the binaries.

On OS X Snow Leopard python normally runs 64bit, unless you have one of the first Intel Macs with Core solo/duo processors.  You are compiling GDAL 32bit.  And without some other env settings Python compiles modules 32+64bit, but you won't see compile errors due to the way it compiles.

Try removing the arch flags so it compiles 64bit.  Heck, no need to explicitly set CC, CXX, ... at all.
