I don't want to introduce yet more ways for two users to think they  
have installed the same thing but in fact they haven't. You're just  
creating more support headaches that way.

gcc-4.0 is the MacPorts default for Leopard now. Let it stay that  
way. (I'm praying Apple won't remove gcc-4.0 in the next Xcode. It  
would be foolish of them to do so.) Let ports that absolutely need  
gcc-4.2 specify that in the portfile with configure.compiler.
