 Do we? I think people are generally familiar with GNU libtool but I for
 one have never really been clear on the purpose of Apple libtool, which is
 the one being used here.

 This extensive [https://forums.developer.apple.com/forums/thread/715385
 Apple library primer] only mentions libtool in regard to creating static
 libraries, which is not what we're doing here.

 The port has used libtool to create this library
 [changeset:88c7ba87cb4912680a4bc62945c2cd6264dbca1d/macports-ports for
 over two decades] but I'm not sure why it does that instead of using the
 compiler.

 I'm inclined to remove the `post-build` block and move the dylib creation
 into the Makefile using a patch, and switch to using the compiler instead
 of libtool, since that's what other projects do.

 The port doesn't honor MacPorts CFLAGS or LDFLAGS. Fixing that will be
 easier if all the building happens in the Makefile.
