Shot in the dark request for help.

I downloaded this, along with Code:Blocks & the latest MinGW.
It doesn't want to link though, and I get the following error:
ld.exe cannot find -lpthreadGC2
I'm guessing it can't see the lib, which is in the project directory.
Can anyone shed some light?

I got TAAs insim demo to build & run.

It has no libs though.
