The current versions all look to be above the compatible versions, so I think you are ok there. However, I'm not sure why they are not the same ... maybe this is normal, but it looks unexpected to me. For now, I'd just assume this is normal behavior.

The errors exist in too many executables and shared libraries to be done manually one by one. I also recompiled Octave with a new LDFLAG -headerpad_max_install_names to reserve enough space for changing all dynamic shared library paths.

However the present problem is that the dynamic libraries refer to the libraries contained in the original path (in mxe directory), and not the libraries inside the app bundle (as reported by otool). I applied your scripts, but they did not work for me. Please see the log of your scripts [1] and the otool output [2].

The stuff in opt/local is not part of the MacOSX system, but is part of Macports. We've probably been through this before, but ... Is there no way to use only MXE compilers and the MacOSX system libraries, which will be in /usr/lib? If not, what is the advantage of using MXE and Macports, rather than just Macports?
