 Yes my tweaks address that issue. This is exactly what I was experiencing:
 the in-build executable failed because the DLYD found the library in
 MP_PREFIX/lib before the one in-build, and that library was too old to
 provide the necessary symbols. The DYLD_FALLBACK_LIBRARY_PATH environment
 variable doesn't work here, since the library is found in the executable
 (confirmed by `otool -L`); one has to use the full DYLD_LIBRARY_PATH
 directly.
