I consider changing compilers like this to be the equivalent of the 
libintl.so.* changes. You have to think that the interfaces in the 
headers have changed and everything needs to be rebuilt using the new 
compiler. Since I updated XFree86 to xorg, I couldn't do a 
portupgrade -pufa easily. The upgrade had to be done more piece meal.

What I have found, with one exception (libxine), is that a -Rf 
portupgrade did wonders on making individual ports compile again. FWIW, 
I am not having any problem building artsd or aspell.
