I've pushed out lablgtk 2.10.0 to F9 (devel) here:
Please let me know if it works for you, and if it does we can have a
look at backporting it to F8.
As for EPEL, I've requested that a bunch of OCaml-related packages go in
to EPEL, but still waiting on those. If those are successful, I'll take
a look at getting access to lablgtk in EPEL too.
