http://meta.wikimedia.org/wiki/Enable_TeX says that
OCaml is required
OCaml : [http://caml.inria.fr/ocaml/release.en.html Latest Objective Caml release] (must be installed in the sub-directory math/ of your wiki)
What does "must be installed in the sub-directory math/ of your wiki" mean?
According to the INSTALL for OCaml, which I attach, OCaml installs into a /bin directory. This directory would need to be in my PATH, I assume.
I currently receive this from the /math directory:
make texvc ocamlopt -c util.ml make: ocamlopt: Command not found make: *** [util.cmx] Error 127
