That shabang line should be #!/usr/bin/perl.

It sounds like you're launching this from a GUI instead of a terminal. You really need to start up an xterm, make your way to the program's directory, and run it from there.

Bask in the glory of the command line. It's one of the reasons why GNU/Linux is so much nicer to work with.
