GD::Graph 2 ...UNDEFINED bug

Trying to run some basic CGI locally without much success. In Mozilla, I just get the source code. In Internet Explorer, I get a mixture of source and the expected html output. If I don't have a webserver configured, is it possible to test this code on my local machine? I don't plan on serving... -
