[LLVMdev] Error when loading omega library with llvm-2.7

Hi Hui Hang,

I don't think there's enough information here for anybody to be able to help
you.  Omega is not part of LLVM (where did you get it from?), meaning that
we can't try to reproduce your problem.  As far as I know LLVM just uses the
standard operating system routines to load dynamic libraries, and it looks like
this is failing, so presumably that symbol really is undefined in spite of what
you say.

Ciao,

Duncan.
