It's true, that's quite confusing. This has it's historic reasoning as
/usr/bin/gcc has ever been the default compiler, so gcc4x actually
refers to gcc versions provided by Xcode. To select versions installed
by MacPorts, you need to use mp-gcc4x.

You can use 'gcc_select -l' to see all versions currently available on
your system.
