I have built the source and binary (i386) RPMs of OCaml 3.10.0 for Red 
Hat Enterprise Linux 4 and 5 and for Fedora 2-6. See 
http://rpm.nogin.org/ocaml.html for the listing of the RPMs.

All packages are signed with my GPG key; the public key is available at 
http://rpmbin.nogin.org/GPG-PUBKEY.txt

You can also download the latest RPMs of OCaml and OMake via yum/up2date 
- just point your client to the appropriate URL from the following list:

http://rpmbin.nogin.org/MetaPRL/fedora-6/
http://rpmbin.nogin.org/MetaPRL/fedora-5/
http://rpmbin.nogin.org/MetaPRL/fedora-4/
http://rpmbin.nogin.org/MetaPRL/fedora-3/
http://rpmbin.nogin.org/MetaPRL/fedora-2/

http://rpmbin.nogin.org/MetaPRL/RHEL-5/
http://rpmbin.nogin.org/MetaPRL/RHEL-4/

A sample /etc/yum.repos.d/Nogin.repo for RHEL5 (i386) is attached below.
