What exactly did you do to set it as the ‘default’ gcc compiler ? port select ? This setting has no bearing on what ports use to build, its only there as a convenience for you, to define what you get as ‘gcc’ at the command line.

Also note that the gcc compilers do not use libc++ as their c++ runtime, but gcc default libstdc++. Mixing both runtimes is a very bad idea, so in fact using gcc is a bad choice. No ports in MacPorts will use it to build C++ sources.

You should instead use one of the clang compilers as your default.

No. Only one is needed for poppler. The others are likely required for the dependencies needed first, before you can instance poppler.
