I looked for something in the MacPorts ticket problems lists, and the closest thing that I can find suggested that it's a setup problem.  I downloaded the Xcode installer from the App Store and executed it (install went fine, apparently, Xcode environment opens with not a problem).

Most likely, Xcode is not installed properly. Reinstall Xcode.

If that doesn't seem to be the problem, do what the log says:

:info:configure See `config.log' for more details.

config.log will be under the directory identified by the command "port work gperf". If you like you can send us the config.log and we'll see what's up.
