Comment:

 Similar to another ticket you've filed, you're probably encountering this
 problem because you've received a binary of one of py27-pyqt4's
 dependencies (I would suspect qt4-mac) which was built on our Snow Leopard
 build server which is using Xcode 3.2.6 and therefore uses
 /usr/bin/g++-4.2, and that dependency bakes this compiler choice into the
 files that it installs, and dependencies use that compiler choice instead
 of the one MacPorts tells them to use at the time. But you have Xcode 4.2
 installed, which does not provide /usr/bin/g++-4.2 anymore. It is wrong
 for build systems to bake compiler values into themselves for use by
 dependencies, but it is difficult to explain this problem to software
 developers and convince them to stop doing so.
