As the error message says, you probably have not installed the Command Line Tools, which MacPorts requires. Please refer to ​the MacPorts Guide for instructions on properly installing the Command Line Tools. Depending on your version of OS X and Xcode, you will either run

% xcode-select --install

or install them via Xcode’s Preferences.

Please don't re-open invalid tickets. Trac is not for tech support. Follow-up on the ​Macports Users mailing list instead.

Okay, so did you look at the link I posted? It has ​directions for 10.8.
