For Lion you could use this, but for Snow Leopard, where presumably Xcode 3.2 is still OK to use, and 4.2 would be ok to use, but 4.0 and 4.1 are not, the portgroup does not model this situation. Perhaps I should enhance the portgroup first, then you can more easily add this error message.

Ok, give me a ping when you've updated the portgroup, and I'll update the Portfile.  I'm fairly certain that XCode 4.0 was fine, and I'm not even sure if the bug was in a shipped version of XCode or just the pre-release of 4.1.  It was a rather short-lived regression, but if it is in a version people are using, we should certainly warn them to upgrade.
