Re: ImportError: No module named Ngl

Hi Jean-Francois,

I'm hoping that the issue is not related to the fact that you
downloaded a PyNGL
that was compiled with gcc 4.3.2, and you are running gcc 4.4.5. I've
never
tried this combo, so I don't know if it will work. I don't have a
PyNGL compiled
with gcc 4.4.5, unfortunately.

First, though, let's make sure your current environment is set up
correctly.

Please let me know what the following reports on your system:

which python
ls /usr/local/lib/python2.6/site-packages
ls /usr/local/lib/python2.6/site-packages/PyNGL
cat /usr/local/lib/python2.6/site-packages/Ngl.pth

and then run python interactively to see what the system path looks
like:

python
import sys
sys.path
<ctrl-d>

Finally, do you have any old PyNGL installations that might getting
loaded
instead of the newer one?
