You could leave the default in place, define a different gcc for the ports 
in /etc/make.conf and then just add to the list of excludes every time you 
run into problems while building a port.
Thats what i do, and so far roughly 80% of the ports seem quite content with 
gcc4.2 
If that sounds cool to you, checkout this sample make.conf out of some german 
Howto. You wont need knowledge of german, Its self explaining enough.
