gcc44 installs correctly but default gcc is still used

[Josie Reinhardt]

 This is probably a very unix newby question so I'm sorry to ask it, but I
 can't find a good solution in the current tickets, guide or via
 googling...

 I followed this guide (http://jswails.wikidot.com/mac-os-x) to install
 macports, and use it to update to v 4.4 of the gcc compiler.  Note that I
 am not doing this for the purpose of using the program that the guide-
 maker is trying to install (amber).  I need gcc4.4 for another reason
 entirely.

 Everything appears to be installed properly based on the output when I run
 "install" and "select" again.  However, when I run gcc, it's clear that
 gcc 4.2 (the default for me) is still being used  (see below).

 How do I get my computer to actually use the ported version (gcc4.4)?
