What version of iPhoto are you currently running and how did you get to that version? Also did Mt. Lion come preinstalled on your Mac Pro? If not what system was preinstalled?
If iPhoto 9 came preinstalled on your MP you might try this source for the updater: iPhoto 9.4.2

I tried to update from the link for IPhoto 9.4.2. This was unsuccessful. My error message said "the version of IPhoto installed on this Mac must be updated through the Mac App store. When I go to the App Store the dowload fails and the message says, "retry download from purchases page". When I try from the purchases page it fails again with the same error message.
My MacBook Pro came with the OS prior to Leopard/Snow Leopard. I updated in stages from that original OS. My original version of IPhoto came with the MacBook Pro. My present version of IPhoto is 9.4.1.
