1. You misspelled "selfupdate"
2. There is no port called "gcc"
3. There is no port called "foo"

And most importantly, there is something wrong with your xcodebuild command, which could be because you did not install Xcode, or did not install it correctly.

None of this suggests any problem in MacPorts, but rather a problem in the configuration of your system or your understanding of how to use MacPorts. Please write to the macports-users mailing list if you require assistance sorting this out.
