Hi Mary,
first of all, thanks for the reply. Unfortunately, this doesn't seem to be the problem.
I first changed the directory in pynglex file, and now it works, but just to give:

Error: I am unable to import the NumPy version of Ngl via
              'import Ngl'

Indeed I did the untar in the /usr directory (and to be sure, I did it again), and ls of the directories

/usr/lib/python2.6/site-packages/PyN*

does give quite a lot of output, among which I see Nio.py, Ngl.py,...

Just to be sure, I checked that I do have numpy installed (it works with 'import numpy', not 'import NumPy').

Thanks for the support,
Andrea

Hi Andrea,

This could be a simple path problem. The pynglex problem is something different.

What does:

  which python

report, and where did you untar the PyNGL tar file from?

You need to untar it in the *root* directory of where python resides.

For example, if "which python" reports "/usr//bin", then
the root directory is "/usr" (and NOT /usr/bin or /usr/lib).

This means you should be in /usr when you untar the file.

To fix pynglex, you can edit the file directory and change 
/d2/haley/external/bin/python2.6 to /usr/bin/python.

It sounds like your python installation is in /usr. Do you 
see anything if you type:

   ls /usr/lib/python2.6/site-packages

and

   ls /usr/lib/python2.6/site-packages/PyNGL

?

Dear users,
I'm not even a beginner of PyNGL/PyNIO, so please forgive me if the
question is silly.

I am trying to install PyNGL/PyNIO on my machine running Ubuntu 10.04. I
am running python 2.6 and gcc 4.4 (which I think is not supposed to be
supported by the binaries you provide).

I followed the installation instructions, but I can't get the modules
working. If I issue "import Ngl" into python, I get "ImportError: No
module named Ngl. If I try to run "pynglex ngl01p" I get:
zsh: /usr/bin/pynglex: bad interpreter:
/d2/haley/external/bin/python2.6: no file or directory

This latter error makes me suspect that the problem is not with gcc, but
with some environmental variable that is not properly set (there is no
such directory as /d2/haley... on my machine).
The installation directory is /usr/lib/python2.6... as the guide
assumes, so I guess this shouldn't be a problem.
What am I missing? Do I need to set up some variable?

Thanks for your help,
Andrea
