This needs a bit more work.

pzstd is written in C++ (C++14). Please have a look at the output of
'make port-lib-depends-check'. I think you need to add
${COMPILER_LIBCXX} to WANTLIB. Additionally, please have a look if it is
needed to add 'COMPILER=base-clang ports-gcc', and if it is needed to
add CXX="${CXX}" and CXXFLAGS="${CXXFLAGS}" to MAKE_ENV.

Most important is that building is tested on arches other than amd64.
Unfortunately, I can not help with that.
