I recently upgraded my Mac Book Pro to Lion and faced challenges with MacPorts application that I had with me. I had downloaded and installed XCode 4.2 from the app store (very un - appstore like installation BTW - you click install on the app store but it only downloaded the app. You need to separately install it) before I did the selfupdate but it does not seem to matter. The application fails with the following errors (relevant sections below) -

As far as I tell I should not be having issues but it looks like I do not have any option but to reinstall MacPorts and all the applications under it.
