Hi C.J. -
It sounds like this perl script is a CGI script being run by a
webserver. Typically, in that case there are more informative error
messages in the error logs of the webserver. If it's apache, that may
be something like /var/log/apache/error.log.
If you have shell acceess to the webserver, you can use SSH to login
to it. Then you can use 'tail' to view the end of the log file. That's
where the most recent entries are. If you use
'tail -f /var/log/apache/error.log'
you may be able to see new log entries as they are added.
You may also want to look into the CGI::Carp module which may help you
get more informative messages in the error logs.
You may find it informative to run 'perl -c' on the files on your
local machine to syntax check them before you FTP them up there.
Hope it helps,
