Lion selfupdate fails

[justindesantis@…]

Hi folks, on a different machine from my last ticket I'm getting the following error when running a selfupdate. Here is the debug output.

I saw a post on usenet (I'm old school) that I should completely remove Xcode and reinstall it. If that's the solution, how do I do that?

"C compiler cannot create executables" usually means Xcode is not installed properly. Ensure you've used xcode-select to select your Xcode installation, and also that you've installed the command line tools, from within Xcode's preferences window's downloads section. Consult MacPorts documentation for further information.

BINGO! That was it! Thanks! selfupdate ran, and now 'upgrade outdated' is running. I'll run the 'uninstall inactive' as well. This will probably take a while on such an old machine! (Late 2006 17" C2D iMac.)
