I'm trying to build CMake on the #atari TT030 overnight, and I'm not hopeful. I've had nothing work on it lately (broken GNU Fortran, problems building IRC clients, a freakin' mess of a network config, etc.), so I'm probably going to break it down and throw it back in the closet when this inevitably fails too.
Once I forget about these problems in a year or two, maybe it'll get some precious desk space again.
But CMake might build...
