while I'm not a Mac use at all, but I have colleques which developed
this code in question on there Mac system and do not have this error.
I can only guess that the used MacPorts GCC is somehow is broken. If
at all this reference to the function comes from inside the C++ STL
headers, not from the to be compiled code. Thus maybe the wrong C++
STL headers are used. Could you provide the preprocessed output of the
otfprofile-create_latex.o target. Than we could check from where the
STL headers are taken.
