http://llvm.org/docs/GettingStarted.html#brokengcc lists documented
problems with different versions of gcc.
I use gcc-4.3.2 with ubuntu 8.10 and haven't had any problems

Yea, I commented out LLVMLIBS at first as well before I came across
the documentation at http://llvm.org/docs/MakefileGuide.html#LoadableModules
.  I think LLVMLIBS is supposed to be ignored when compiling a shared
library but somehow isn't.  I'm new to LLVM so I could be way off.
Best of luck!
