Comment (by kencu):

 did you fix your leopard sdk?

 https://trac.macports.org/wiki/LeopardSDKFixes

 once you do, your missing symbols should be found.

 The type_traits issue has to do with the c++ standard not being set. gcc
 defaulted to c++11 as of about gcc5. clang defaulted to c++03 until about
 clang-10 or so, then defaults to c++17 after that.

 So best to just set the c++ standard you want (need) to avoid these
 differences.
