I needed to “compile” a latex document using the tkiz package. After spending quite a few time trying to set this up on CentOS and Fedora, I finally gave up. Fortunately Ubuntu had a working pre-built package that includes pfg and tkiz, but this also required two online searches to deal with latex errors. A summary of the process for RHEL/CentOS/Fedora  I searched many times for RPMs with tkiz/pgf for RHEL 5 or FC12 (to install it on our CentOS server).
