Comment (by barracuda156):

 Replying to [comment:8 kencu]:
 > barracuda, can you try building ICU outside of macports with your
 handmade gcc7 (and if that fails, one of the newer ones)?
 > If any of your gcc versions inside or outside of macports can build icu
 64 bit, let me know.

 Sure, I will try and update you here. (Sorry for delay, I was away from my
 PPC machine.)
