The downloadable rpms are for both [http://www.redhat.com/ RedHat] and [http://fedora.redhat.com/ Fedora Core] (both 1 and 2). I found that these RPMs have a number of problems and do not rebuild - for information see #1141 I would recommend that if you want directly installable RPMs with all the dependencies correctly handled (and available within the same repository) you use the RPMs within the Dag/Rpmforge repository at http://dag.wieers.com/packages/trac/ (the information for setting up ''yum'' for this repository is at http://dag.wieers.com/home-made/apt/FAQ.php#B ) TracOnFedoraCoreThree For information on setting up SELinux for Trac, see TracWithSeLinux.
