Description of problem:
Current git in git.gnome.org (which uses RHEL 5) can't highlight Vala files[1]. That's because RHEL5 ships highlight 2.6.12 while Vala support was added in 2.6.14 (dated 21-October-2008). Hence my request to update highlight package to 2.6.14 version to support Vala language.

I filed this request as suggested in downstream bug https://bugzilla.gnome.org/show_bug.cgi?id=643283
