Head over to http://www.sunfreeware.com/, grab a binary of GCC, install it in your home directory, edit your PATH, INCLUDE, and LD_LIBRARY_PATH shell variables and get cracking.

There's also a tutorial around somewhere that gives you instructions on how to install Perl modules into your home directory.

Finally, don't forget that most Sun machines are binary compatible, so you can compile modules on your dinky Ultra workstation and upload them to your enterprise servers, where they will work just fine.
