SBCL is supported under PPC/Linux, Alpha/Linux and SPARC/(Linux|Solaris)
currently... ports to Tru64 and MacOS X are either in the works or being
thought about. I think Dan Barlow has sbcl/clm working on his PPC to the
extent of playing with delay effects :-)

OpenMCL is, in my experience, beginning to get into shape; one of the
things about working on a large system like a lisp compiler that is
allegedly portable is that implementation bugs are exposed quickly in
both directions... as of version 0.11 of OpenMCL, it is a bug (or three)
in SBCL that prevent it from being cross-compiled successfully. Or, in
other words, "OpenMCL is a good-quality ANSI CL". As for its FFI, I'm
afraid I haven't really played with it much, but I would be surprised if
it weren't in good shape... though, again, it is a "0." version so the
interface might be subject to change. There is a developer mailing list
for openmcl, too (openmcl-devel @ clozure.com) which will be more able
to fill you in on the details than I.

Cheers,

Christophe
