The problem is multilayered, I am kind of confused as to how I'd go about solving this. Here are the issues:
It's a 64bit server, which means it needs to be recompiled. The sources to the older versions of the compiler do not exist, and I don't have time to fix most of the bugs in the 2.5.0 compiler. Even if I do, we need to use the new compiler ANYWAY so 64bit plugins will work for the 0.20 release.
Basically, all this comes down on to me waiting for Thiadmer to help me out. he is the small maintainer
