If the RPM supplied by your distribution is not sufficient for whatever reason you can easily recompile it using the source RPM. Here is an example session with Pound which is only provided as a source RPM:
> yum -y install rpm-build
> wget https://www.invoca.ch/pub/packages/pound/pound-2.4.4-1.src.rpm
> rpmbuild --rebuild pound-2.4.4-1.src.rpm
> cd /usr/src/redhat/RPMS/i386
> yum --nogpgcheck install pound-2.4.4-1.i386.rpm
> rpm -ql pound
You have to disable the signature check because you haven’t signed the package yet.
