Working with directories - thanks

Thanks to all for their help.

I think the clear answer is that putting modules and data into User space
was a mistake. And that using directories in "System space" and absolute
pathnames will cure my headaches.

Scream if I still don't get it...

(Script saved in /usr/local/bin)

#!/opt/perl/bin/perl -w
use lib qw(/site_perl);
use MY_MODULE;  
open (IN, "/var/input/raw.txt") or die "Failed to open input file: $!\n";
....
