It works for me switching between gcc46 and gcc47. I don't have gcc48 installed. gcc48 may be special because it does not install java or fortran by default, and those two cannot be installed simultaneously; this may be related to:

Does "sudo port select --set gcc none" properly delete the gfortran and other links? If not, delete them manually. Then you should be able to select the desired version.
