I have just uploaded a new version of cl-muproc. It's a tiny change due to a problem reported by Masayuki Onjo: if cl-ppcre is installed, muproc-find now takes arguments of class `string' instead of `simple-base-string', which Allegro does not have (it has a type of that name, but not a CLOSS class so we can't specialize on it). -Klaus.
