This was the patch that we added for Fedora to fix the relevant META file: http://cvs.fedoraproject.org/viewvc/devel/ocaml-findlib/ocaml-findlib-1.2.3-camlp4-META.patch?revision=1.1&view=markup (Although more recent versions of findlib include the necessary correction). So you could try the patch above, or try a later version of findlib. Rich. -- Richard Jones Red Hat
