Re: ImportError: No module named Ngl

I have a feeling there's an incompatiblity issue with the version of gcc.

Which version of numpy are you running? I'll see if I can build a PyNGL
on a system that's closer to yours, but I'm not sure when I can get to
it.

Of course, you can try building PyNGL yourself from source code, but then you'll
need to install NCL, and you may have the same incompatibility
problems.
