I'm just another user and I think that this ticket falls in line with the instructions given on: ​https://trac.macports.org/wiki/ProblemHotlist "If the below workarounds enable you to install a port that failed with its default compiler, file a ticket and let us know so we can fix it."

As you may gather from my shell dump, I couldn't use the default manner so I had yo use your prescribed (​https://trac.macports.org/wiki/ProblemHotlist) workaround:

$ xcode-select -print-path /Applications/Xcode.app/Contents/Developer

@pulkitsinghal, you're clearly on Lion, so if you're experiencing an issue, please file it separately.

I'm actually going to close this because we're considering just making apple-gcc-4.2 default on Tiger anyways, and I'll need to go remove all these blocks.
