I don't know if Ruby needs it, but I ran into a similar issue for Python
2.6 in EPEL 5: the configure.in required autoconf 2.61.  

To get around this, I set up the python26.spec file to make it easy to
regenerate this file on a Fedora box with a more recent autoconf.

grep for "regenerate_autotooling_patch" in here:
http://cvs.fedoraproject.org/viewvc/EL-5/python26/python26.spec?revision=1.2&view=markup

which also has links to docs on getting the newer autoconf.

Hope this is helpful
