A tip to reenforce [Abigail's sentiments:

You can test your CGI scripts by running them from the command line before you deploy them. If the script needs command line parameters, supply them via the command line as well. If you pipe the output to a file, you can check the results by looking at the out with a browser. The best bit is that you will see any compiletime or runtime errors at the terminal rather than having to search the logs

See the CGI.pm code for more info.
