xcodebuild not functioning is just a warning at this point and the gcc47 port seems to install and activate fine from the output above.

If you wanted to activate gcc47 that would be "sudo port activate gcc47" not "sudo port activate gcc4.7", still from the output above I'm not sure why you'd want to since it, again, installed and activated fine.

For recent problems relating to Xcode 4.3 and xcodebuild there is some documentation at https://trac.macports.org/wiki/ProblemHotlist#xcode43 that can help you to sort out a functioning xcodebuild and remove the warning.

$ port variants gcc47
gcc47 has the variants:
   gfortran: Enables Fortran/gfortran; this language will be enabled in the
             final version - this variant is completely untested!
     * conflicts with java
   java: Enables Java/gcj; this language will be enabled in the final version -
         this variant is completely untested!
     * conflicts with gfortran
   universal: Build for multiple architectures

Installing gcc with: "sudo port install gcc +gfortran" would have compiled it with fortran support.

hope that helps,
