A Norway Government Institution asked me to fix the pgRouting package for PostgreSQL 9.2 on RHEL 6. Their name is "Norsk institutt for skog og landska".
Packaging was not that easy, since they asked me to add "Traveling Salesperson functionality" and "Driving Distance functionality", which required gaul and CGAL packages respectively. CGAL is available in atrpms.net, but the gaul-devel required by TSP functionality required a custom slang, which is actually compat-slang, and because of the termcap changes in RHEL 6, I had to build a custom compat-slang package to build gaul-devel
Anyway, packages are now available for PostgreSQL 9.2 on RHEL 6 x86_64 and RHEL 6 i686. I am also planning to push the package for 9.1 sometime this week. Fedora 17 packages will also be available in preparation for next year's RHEL 7!
Thanks "Norsk institutt for skog og landska" for contributing to community packaging.
