Dear Matt,

I checked the log file but didn't see any error message. I don't know if it's because I succeeded in installing Athena and Artemis following Carlo's suggestion and the log file is thereby updated. Here's the content of the log file:

"#!/bin/sh
# PGPLOT install log
# system =  linux  ==  linux g77_gcc
# prefix =  /usr/local/
# fortran compiler =  gfortran
gzip -dc  pgplot5.2.tar.gz | tar xf -

I hope the length is not too bothering and thank you very much for the help!
