Data::Dumper is really quite easy to use:

use Data::Dumper;
print Dumper $some_var;
[download]

You said this was for a CGI script, if you have access to the error log, you can tail -f it and print to STDERR:

print STDERR Dumper %hash_of_hashes;
[download]

If you don't know what the error log is and would rather just print it to the browser, be sure and use pre tags:

print "<pre>\n", Dumper %hash_of_arrays, "</pre>\n";
[download]

Hope this helps.
