Well, the latest is available at
http://svn.ruby-lang.org/repos/ruby/branches/ruby_1_8/lib/mkmf.rb

However, I found all sorts of things didn't work with 1.8.1 (which is 
really ancient), so under RHEL 4 I moved to the 1.8.5 packages from the 
CentOS testing repository: 
http://dev.centos.org/centos/4/testing/i386/RPMS/
and everything was fine. If at all possible in your situation, I'd 
strongly recommend it.

Regards,

Brian.

P.S. To get even more up-to-date, you could consider rebuilding the 
RHEL5 or Fedora packages for CentOS 4. You need to change one line in 
the .spec file (dependency on libX11-devel needs to be changed to 
xorg-x11-devel)
