Hi Russ -

thanks for the feedback, this is good to know.

I did get netcdf to compile successfully last night. Two
changes I made:

1. set -YCRFL=1, not -YCRFL=l , i.e. set it to one, not "el". previous 
mistake
on my part.
2. explicitly set CC=/usr/bin/cc. I don't know if this is really necessary,
but it didn't hurt.

Otherwise, I followed Dierk Polzin's recommended build. I believe
that fortran code calling netcdf also needs to be compiled with the
-YCRFL=1 flag (not mentioned on his build).

This process somehow removed my IDL license file and IDL path ! That
was odd, probably a poor previous installation on my part, but still. I
wasn't completely done with this project until I relearned how to install
the IDL license, but, now things seem to be fine.

Thanks again - seeing that this process isn't completely transparent 
even to a
trained professional as yourself helped me to persevere.

Paquita
