Dealing with this stuff is hell. One of the issues is that it is
always unclear whether the main file cannot be found or one of its
dependencies. I'd set DYLD_LIBRARY_PATH to include (besides the
default stuff) the directories holding the Java .dylib and the Prolog
.dylib directories. Verify that you can load jpl.dylib using
`otool -L /path/to/jpl.dylib`

Some people have it running on MacOS ...

Hi everybody

For every one who use mac, i found the solution for this problem, is quite simple but i spend to much time find it out so i want everybody let know how to do it.

First of all , swi prolog must be install as macports, not normal installation

port install swi-prolog

if you dont have install already macports command not found will apear so go to https://www.macports.org/install.php and install macports

after install swi prolog via macports, you only have to navigate to the path of swi prolog macports installation which mine is /opt/local/lib/swipl-6.6.6/lib/x86_64-darwin14.0.0 copy this path and set in java.library.path in the java VM as  -Djava.library.path=/opt/local/lib/swipl-6.6.6/lib/x86_64-darwin14.0.0

with this it will work find , please Jan tell people that, it was a waste of time for me and i want to avoid this for other people.

Thanks a lot. Cheers- Frank
