The "ps3bodega" repo, forum, etc. is temporarily unavailable. They tell me it will be up again "shortly" but I don't know exactly when.
For anyone using the ps3bodega repo, for the moment you'll need to disable it if you're trying to install software via yum or the "Add/Remove Software" feature (pirut or yumex). That means edit the /etc/yum.conf.d/ps3bodega.repo file and change enabled=1 to enabled=0.
EDIT: All back up and running now!
