The Beta C compiler is downloadable from: http://software-dl.ti.com/codegen/non-esd/downloads/beta.htm
under the "PRU Code Generation Tools" section. IIRC, you need to create a log in and fill in a request form. There's also a project to port GCC located at: https://github.com/dinuxbg/gnupru that I've not yet tried.
