You should be able to just install the x86 version. If your old install
and your new install are both .tgz installs, then your new install will
simply overwrite the old files. The two packages should have almost
identical file lists. IIRC, the only difference should be that the old
install will have
/usr/local/lib/mlton/sml/basis/config/c/ppc-darwin
while the new install will have
/usr/local/lib/mlton/sml/basis/config/c/x86-darwin
You can delete the ppc-darwin directory that was migrated from the old
install but not needed by the new install.
If your old install is a .dmg install, then I believe that there is a way
to uninstall the old version before doing a new .dmg install. But, I'm
not familiar enough with the MacOS X packaging to be sure.
