Is there any documentation on this error somewhere?
I have no idea what it means.

The first module (Metl) contains a functor, and
the second one (MetlString) supplies an argument module
and calls the functor. Both of them extend the PreCast
parser.

I had a similar problem recently. In my case, it was resolved by
upgrading ocaml from 3.12.0 to 3.12.1. Apparently, camlp4 is buggy in
3.12.0 (so I was told, and upgrading fixed the problem for me)
