And you could probably automate the whole process with:
port installed variant:gcc48 | awk '/\+gcc47/ {print $1}' | xargs -n 1 -J %
sudo port -y upgrade --enforce-variants % -gcc47 +gcc48
This:
* gets the list of installed ports that have a gcc48 variant
* using awk, prints the names of those that were installed with the gcc47
variant
* upgrades each one to use gcc48 instead of gcc47
