Fortran Installation

[Lou Umscheid]

wow; thanks for quick response. I tried running your first command but 
got the message:

awk: fatal: cannot open file ' /etc/setup/installed.db' for reading (No 
such file or directory)

The file seems to be there and I checked my input so I do not know what 
when wrong. Any suggestions?
