To add on to Ryan's statement, gcc versions typically do a good job of isolating themselves from each other (if this is what you're worried about). If you install multiple gcc's alongside each other, the libraries and headers and such will be placed in a version-specific folder, and the real binaries will have version-specific names.
Coupled with gcc_select (another port package I would suggest installing to have multiple GCCs), you should be able to have as many GCC versions installed at once as you want. To demonstrate, on my system: $ gcc_select -l Available versions: gcc40 gcc42 llvm-gcc42 mp-gcc43 mp-gcc44 mp-gcc45 mp-gcc46 and I can seamlessly switch through them as I want.
