Re: stuck on install

I had to link the PyNGL directory to Ngl as well.

# cd /usr/local/pyngl/lib64/python2.4/site-packages
# ln -s PyNGL Ngl

Now "import Ngl" works without error, but I am getting the following:

# pynglex -a
Traceback (most recent call last):
  File "/usr/local/pyngl/bin/pynglex", line 118, in ?
    os.environ["NCARG_NCARG"] = Ngl.pynglpath("ncarg")
AttributeError: 'module' object has no attribute 'pynglpath'
