Latest on WN SL4/64 upgrade

I've created a gridpp wiki page which lists the cfengine config we're using to satisfy various VO requirements. Things have changed recently with Atlas no longer requiring a 32 bit version of python to be installed, it's now included in the KITS release. We still have build problems with release 12.0.6 as used by Steve's tests so would be interested to see how others get on with that. The Atlas experts advise a move to the 13.0.X branch. Atlas production looks healthy again with plenty of queued jobs for the weekend so hopefully smooth sailing from now on.

Advice to Atlas sites upgrading to SL4/64:

• Install packages listed here: https://twiki.cern.ch/twiki/bin/view/Atlas/DAonSLC4

• Expect failures when building code with release 12.0.6
