Hm... I played around with camelbox, and I guess I'm just baffled. I went through the checkboxes over and over again and never found any option to install Perl/Tk. Are we talking about different versions of camelbox or something? The one I found was camelbox_2008.304.0742Z-odin.exe. I also tried using camelbox's CPAN.pm to install modules, but it didn't work.
