As far as I'm aware, JadenKorn is maintaining a linux build. If I see him in IRC I'll point him in your direction.

Currently the Linux build only works for the internal team revision, but it is planned to be released to the public along with the Mac OS X build. Sadly, the current public SVN revision is quite outdated, you will face many problems compiling it. But as soon as Public Beta 2 will be released, both the binaries and the source codes will be released to the public as well. Also a 64-bit of the Linux binary is currently under development (have to fix an discomforting bug regarding spawning). Everything else looks great, tried on quite a few popular Linux distros, and it should work quite well on all of them.
