glite UI update fix

To resolve the missing dependancy on the ui for the last two updates of glite
in particular the glite-ui-config rpm required python-fpconst.
You can get this rpm from cern see:

http://linuxsoft.cern.ch/repository//python-fpconst.html

Use
wget http://linuxsoft.cern.ch/cern/SLC30X/i386/SL/RPMS/python-fpconst-0.6.0-3.noarch.rpm

to add this to your local repository.
Then yum -y update will work once again.
