[Jean-Claude Passy]

Hi all,

I am having trouble installing the current dev version. I get the following
error:

I am on OSX 10.8.2, with gcc 4.7.2 (but I have also tried the build-in
version 4.2.1).
I have tried turning on the different NUMPY_ARGS, but it did not help.

Does anybody have an idea how to fix this?

Thanks a lot guys,

JC
