You now need to install Mercury with asm_fast.par.gc for MCORBA to work.
omniorb has gone drastically multi-threaded and so you need the
threading support that is in the asm_fast.par.gc grade.

To install asm_fast.par.gc, you run

	mmake install LIBGRADES=asm_fast.par.gc

from the top level of the Mercury source.

Are you sure you have installed the CVS build of Mercury and you are
using it?  It looks like an earlier version is in your path (e.g.
something many months old -- possibly 0.9.1).

I just downloaded MCORBA 0.3 and built it just fine using 
Mercury Compiler, version rotd-2000-11-02, configured for i686-pc-linux-gnu
so my first guess is that your installation is a problem, but let me
know if it appears OK and we can look into it further.
