The closest I could come searching was this problem: #35506

I should note that I'm quite a novice. I just installed MacPorts for this specific program (gqrx) earlier today.

[ryandesign (Ryan Carsten Schmidt)]

The problem seems to be that although MacPorts has told py27-pyqt4 it should use the llvm-gcc-4.2 compiler, the log shows it's actually trying to use the gcc-4.2 compiler, which does not exist in Xcode 4.2, hence the "No such file or directory" error.

I'm guessing this is because qmake is being used somewhere. qmake has its own ideas about which compiler it should use: it thinks it should use the compiler it was itself built with. In MacPorts, this assumption can be incorrect, such as in your case where you received a binary of qmake from our Snow Leopard build server (which uses Xcode 3.2.6 and therefore has and uses gcc-4.2) but are now trying to compile something from source with it on your system with Xcode 4.2 (which doesn't). Each port that uses qmake must therefore instruct it to use the correct compiler. For many ports, the qmake portgroup can be used to accomplish that; for others, it must be programmed manually.

Guessing this ticket is no longer an issue, so closing as "fixed" sometime between now and then. If I'm incorrect, please reopen the ticket and provide an update.
