I got bit by this tonight as part of testing a patch on CentOS 5, which
like RHEL 5 still ships flex 2.5.4. I just wrote a little guide on how to
grab a source RPM from a Fedora version and install it to work around that
problem:

Kind of annoying, but as special software you have to install on a server
just to build something from CVS goes it's only a minor inconvenience.
