Looks like you're so good at linux, then you could probably just read the makefile, know that there are dependencies missing and grab the source file. Piece of cake with Linux right?
I don't like the additude towards Microsoft, just because coders use it. I code on Windows , Mac and Linux. And i don't care what OS it is, as long as it works.
RealBot was re-released with a purpose to give out an official, easy to install (for Windows yes) latest version. Instead of just downloading an old version, incremental updates, etc.
Source code is delivered with it, with a bit effort you can get it compiling for sure. Hint: Metamod, HLSDK.
