Unfortunately the waf-tools helper library doesn't support "c++" as the c++ compiler. I'm not familiar with freebsd, but on ubuntu c++ is just a symlink to g++. You can force waf to use a different c++ compiler like so:

CXX=g++ python3 waf configure

Alternatively you can just use CMake to build the library instead.
