Obviously, it means that GnomeMeeting links at runtime with a different library
version than the one it has been compiled for. Try ldd gnomemeeting to see
if it picks up the correct library, and also make sure that you have
the correct versions of libraries compared to GM.

I don't think it is the same problem. I don't really know what happens exactly
with the symbolic link. I only know that it fails (or hangs), when creating
the PWlib PProcess. I'll mail Equivalence about that.
