Comment (by kencu):

 I am still not able to get past this error -- it has to do with c++
 templates being instantiated in multiple cpp files. Apparently somehow
 this can work, but not with gcc7 on Tiger or Leopard it doesn't.

 If anyone has any insight into this magic, love to hear about it. Probably
 only Michael or Ionic know enough c++ to work through this one.

 In the meantime, all I can think of to do is roll back to icu @65 pending
 some kind of resolution. That is what I've done in my own repos...
