CentOS - Jun 2007 - Has anyone gotten KDiff3 to work on CentOS 4.X?

The Subject: line says it all.  I haven't been able to find a KDiff3  
RPM (http://kdiff3.sourceforge.net) that will install on CentOS 4,  
and I am also having problems building it from source (the  
application that is, not the RPM).  I have some users who really want  
to use KDiff3, so any help/hints are appreciated.

Thanks,
Alfred
