Well, I wouldn't have thought that you were even able to install
the cm3-min-POSIX-PPC_DARWIN-5.4.0.tgz system on an Intel machine;
it's surely not supposed to run on one. It shouldn't be too 
difficult to get a port of the latest CM3 for Darwin on Intel
processors; I even think somebody was already working on it,
but I don't really remember who, so I forward your mail to
the m3devel list, in case others have already started such an
effort.
