This fixed it.

sudo ln -s /usr/bin/gcc /usr/bin/gcc-4.2

I'm on SL 10.6.8 and XCode 4.2, 2011 i7 MBP

As I told you in the other ticket, don't make such a symlink. Please delete the symlink again.

What does the config.log say?

It is unusual that it decided to use /usr/bin/gcc-4.2 as the compiler, if that did not exist; indeed, it is not expected for any gcc to exist in Xcode 4.2 anymore. Apple now only ships llvm-gcc-4.2 and clang.

[macports@…]

Well I'm not in a position to say now, having since rerun it with the hack. Are you talking about sources/rsync.macports.org/release/base/config.log? If so its been nuked by the successful update. You want me to uninstall it and have another go?

[ryandesign (Ryan Carsten Schmidt)]

You could remove the symlink, then force MacPorts to try selfupdate again. "sudo port -f selfupdate". If it fails then you can look at the config.log.
