Maybe I should mention that I just finished testing all Python
packages in EPD under 10.7, and everything (execpt numpy.sqr
for weird complex values such as inf/nan) works fine!
In particular building C and Fortran extensions with the new LLVM
based gcc and importing them into Python (both 32 and 64-bit).
There are two MacOS builds of EPD (one 32-bit and 64-bit), they
are compiled on 10.5 using gcc 4.0.1 and then tested on 10.5, 10.6
and 10.7.
