The error is:

model_context.cpp:20:39: error: unknown type name 'nullptr_t'; did you mean 'std::nullptr_t'?

Maybe the error message is right and it should be using "std::nullptr_t" instead of "nullptr_t" (or "using namespace std", though this is not recommended).

P.S: As a general recommendation, disable the silent rules in this port so that we can see the compile commands in the log.
