I seem to be unable to select a macports downloaded gcc compiler. The Apple
XCode supplied compiler doesn't work with the program I want to compile
(MrBayes), so I downloaded one that should work from MacPorts. I'm new to
macports and could use some help. 

I think that I am turning on the compiler here:

sudo port select --set gcc mp-gcc45

but when I enter gcc -v I see that the old mac version is still default. 

How do I compile a program using gcc4.5?

Thanks in advance
