I recently upgraded from snow leopard to lion. I've got the latest version of Homebrew running (e.g. I ran 'brew update'). I'm trying to install mysql but I get the error below.
Googling for how to fix this has turned up nothing...

UPDATE
I think thinks may be related to conflicting versions of XCode. I've installed the latest version fo XCode, but homebrew still thinks I have the old version installed
Warning: You have Xcode-3.2.6, which is outdated.
Please install Xcode 4.3.
Attempting a fix....
