The MacPorts clang-2.9, -3.0 and -3.1 ports are very new, newer than MacPorts 2.0.3, so MacPorts 2.0.3 does not contain these values for configure.compiler. These values were only added to MacPorts trunk in r86719 on November 1; you can build MacPorts from trunk if you want to try these values. Or you can manually set configure.cc and related variables to the corresponding values in your Portfile.
Note that clang and llvm 3.0 were just released in stable version December 1, and those MacPorts ports have not yet been updated to that version. 3.1 is likely to be very unstable at this point.
