Fabio,
It is better to conduct such exchanges on gradsusr so that we have a
record of it for future reference.

Hi Arlindo,
finally also galab works fine!
But only using Fedora11 Linux distro (not FC10), python 2.6 (not 2.5),
pygrads-1.1.3 and grads-2.0.a7.oga.2-bundle-x86_
64-unknown-linux-gnu.tar.gz...
Anyway, thank you for your support, unfortunately there is not much
information (about problems) online...
Fabio.
