[CentOS] Unable to run yum update

Folks

The system involved is a 32-bit system, installed via the net about a 
week ago.  The command

   yum update

encountered the following diagonstic

Error: Package: yaf-1.3.2-1.el6.rf.x86_64 (@rpmforge)
            Requires: libfixbuf-0.9.0.so.8()(64bit)
            Removing: libfixbuf-0.9.0-1.el6.rf.x86_64 (@rpmforge)
                libfixbuf-0.9.0.so.8()(64bit)
            Updated By: libfixbuf-1.0.1-1.el6.rf.x86_64 (rpmforge)
                Not found
  You could try using --skip-broken to work around the problem
  You could try running: rpm -Va --nofiles --nodigest

The repositories I use are:

base
epel
extras
rpmforge
updates
virtualbox


I wonder if using priorities would help?  Rpmforge is "supposed" to 
be non-conflicting, but then....

Please let me know what I should do.
