Actually, you would need to install it in /usr/lib/mlton/.  Also, note
that you can't generally replace the mlton-compile executable (or
mlton-smlnj.x86-linux heap) from one version of the compiler with
another version, since the runtime library, basis library, etc. may
have also changed.  If /usr/bin/mlton and /usr/lib/mlton correspond to
mlton-20070826 (as might be the case if you installed them from your
Linux distribution's package manager or if you installed it from
mlton-20070826-1.x86-linux.tgz from mlton.org), then this will almost
certainly not work.

Generally, the best thing to do when self-compiling is to run the
resulting compiler directly from build/bin/mlton.

Looks like something got corrupted in your mlton script.  Has it been
altered from that in SVN HEAD?
