Comment:

 I am not clear about whether you are encountering the problem when
 building a port in MacPorts (which port?), or when building software
 yourself outside of MacPorts (which software?) but using libraries
 provided by MacPorts ports.

 I see a reference to /usr/local/lib/octave/7.0.0/liboctave.8.dylib in your
 output. Note [wiki:FAQ#usrlocal our stance on having things in
 /usr/local].

 I see that you appear to be building whatever it is with g++. Note that
 you cannot mix and match C++ compilers. You must either compile everything
 (including dependencies) with g++ or with clang++, not with a combination
 of the two.

 MacPorts ports will build with clang++, except in unusual circumstances.
 There is no supported method to request MacPorts to build with g++
 instead. We recommend using clang++. The octave and SuiteSparse ports in
 MacPorts do appear to be unusual in that they offer you variants to let
 you choose which compiler to use.
