The first I saw of it was a note in the RVM installation that indicated 4.2 would not build some rubies and gems correctly. I recently got a new Mac with Lion and installed 4.2 before installing MacPorts and some ports. One of the first ports I installed was PostgreSQL 9, and when trying to access the server via psql, I encountered a segmentation fault. Some googling around suggested the problem was Xcode 4.2, so I went back to 4.1 and haven't had any problems. My point in all this is that you might possibly encounter some problems with Xcode 4.2.

The problem is not Xcode 4.2 per se, but the fact that we use clang by default when using Xcode 4.2 and up. Some ports don't compile properly with clang, or compile but don't run properly. When you identify such ports, please file tickets in the issue tracker.

Upgrading from Snow Leopard should not have been a big problem. Upgrading from Leopard or earlier was what I was talking about. But I'm glad you got things working by rebuilding everything.

Yes, it can take some time to rebuild all ports. Sorry about that. This will improve once we get a Lion buildbot set up, so that MacPorts can just download binaries instead of having to build them.
