This seems like an interesting idea, though I think you'd also want to  
tie it to a global configuration setting so that you could compile  
MacPorts as a whole against a specific compiler (unless the port  
itself overrode this, perhaps knowing itself to be broken unless a  
specific compiler was used).  This could be useful for validating new  
compilers or even trying experimental compilers like gcc-llvm and  
seeing how many ports fail to build.  In other words, the platform  
check is a reasonable default, but I can see an admin on any platform  
version wanting to override this default without having to edit the  
Tcl.   Since gcc_select was retired, may it rest in peace, this  
configuration knob becomes even more important.
