OS X Lion upgrade awesome but broke my python dev environment

OS X Lion brought some substantial improvements but required pretty much my entire development environment to be rebuilt.  Python got upgraded to 2.7 and required all of my modules to be reinstalled.  Apache wouldn't start because mod_fastcgi isn't provided for Lion.  XCode had to have the new version reinstalled and then the command line tools package installed to get gcc back.  I wish I would have known this before upgrading so that I was prepared.  It's well worth the upgrade and the inconveniences that come with it but just beware that your system will definitely require some additional setup after upgrading.
