#10

I didn't know about the lipo tool, but according to the lipo command,
the python 2.6 executable has x86_64, i386, and ppc7400. If it gets
executed in x86_64 mode, then loading the etree.so file for the lxml
extension must obviously fail, because it only contains the i386
extension. It shouldn't be too hard to compile the libraries in x86_64
mode and add that architecture to the files.

The python 2.6 binary is a 'Mach-O fat file with 3 architectures', while the etree.so shipped with lxml is a 'Mach-O fat file with 2 architectures'. I suspect that the 2.6 binary is running with the x86_64 architecture, which isn't present in the etree.so library.
