Tonight, right before I started trying to compile my dissertation, ConTeXt ate itself. I have determined that the maintained version of ConTeXt in the ubuntu distribution is of appropriate vintage to probably work.
My only problem is that I use the "simplefonts" module and I'm not sure how to install it within the ubuntu context.
What mechanisms exist for adding third party modules to this distribution of ConTeXt?

tlmgr? Otherwise, you can consider installing ConTeXt standalone in a parallel tree. See ConTeXt wiki for details. – Aditya Mar 26 '12 at 14:35
