Comment:

 The issue "Mac with system libffi" is a duplicate of #7686.

 A patch for #7686 is currently under review.

 The two issues "without system libffi" were solved in Linux by adding an
 ELF rpath/runpath to
 the library if a library was not installed in a linker standard directory.
 I believe the same would work for any ELF system and IIRC FreeBSD uses
 ELF, too. Do we have a conditional to
 check for ELF system (instead of Linux as done now) in our build system?

 I don't know enough about mach-o to provide a "Mac without system libffi"
 solution.
