nx-libs-3.5.0.22-1.el6 belongs to x2go. See rpm -qi nx-libs-3.5.0.22-1.el6. In my opinion, this package does not make sense for Freenx:

rpm -ql nx-libs-3.5.0.22-1.el6

/etc/ld.so.conf.d/nx-libs-i386.conf
/usr/lib/nx
/usr/share/doc/nx-libs-3.5.0.22
/usr/share/doc/nx-libs-3.5.0.22/COPYING
/usr/share/doc/nx-libs-3.5.0.22/LICENSE
/usr/share/doc/nx-libs-3.5.0.22/README
/usr/share/nx/SecurityPolicy

Have you talked to the epel folks?

Cheers,
