Meanwhile, the build with the configure-less version of the Portfile is
making a token attempt at setting install_name (incorrectly) while using
filenames as though it's on Linux:

c++  core/desugarer.o core/formatter.o core/lexer.o core/libjsonnet.o
core/parser.o core/pass.o core/static_analysis.o core/string_utils.o
core/vm.o third_party/md5/md5.o cpp/libjsonnet++.o -shared
-Wl,-install_name,libjsonnet++.so.0 -o libjsonnet++.so.0.14.0

It pulls in all the needed .o files at least...
