The main problem with RHEL and Ruby on Rails is that the version of
Ruby available for EL6 from reputable repositories is too old.  RoR
3.2 can get by on 1.8.7 but support for Ruby versions prior to 1.9.3
is being dropped in the forthcoming RoR v4 release.  Thus, a
RHEL/CentOS rpm package for Rails really will not give you much, if
anything.

I suggest that you investigate both RBENV and RVM as alternatives to
using the rpm packaged Ruby. I advise you consider that for RoR
projects the Bundler gem is the preferred way of installing and
managing project specific packages, including Rails itself.

The down side to this approach is that your production servers need to
have development tools installed to build the Ruby interpreter and the
support gems.  The up side is that you can version specific ruby vms
and gemsets on a project by project basis.

I used rvm almost from its inception but have recently changed to
rbenv as this has a much smaller footprint on the user's environment. 
But both are excellent products.  If you are installing RoR for a
production environment then you will almost certainly need to consider
using Passenger (mod-rails) as well.
