Following on from a conversation in the COs chatroom the other day, the cpanspec package is now available for FC6 machines. If you run updaterpms on a “develop” DICE machine it will get installed along with the various dependencies. This is a recent version (1.73-1) from F8 so should be up to date with the relevant standards. I’ll look into building the necessary packages for SL5 as well.
Update: The same version of cpanspec and all the dependencies are now available for sl5 as well.
