Please note that this is NOT what the mud is running, there have been many, many, modifications and improvements to it. The source code the mud runs on is not released at all, do NOT ask!
No immortal on the mud will help you compile the code; you're on your own. This is a test of willpower - only the worthy manage to compile the code. That being said, it should compile fine on most Unix-like environments.
