hmmm, working on a x86_64 box ? 
Have you installed from scratch or have you made an upgrade ? if so,
have you followed this 'manual update' ? :
http://lists.centos.org/pipermail/centos/2007-October/088312.html

Which versions are actually installed and for which architectures ? 
rpm -q nx freenx --queryformat %{name}-%{version}-%{release}.%{arch}\\n
