This is the more exact message that I get when I try to install the mod:
Attempting to run mosunpack from the mod directory...
dyld: Library not loaded: /usr/local/lib/libjpeg.8.dylib
Referenced from: /Users/jasonlong/Beamdog Library/00783/bp-bgt-worldmap/bin/osx/mosunpack
Reason: image not found
How do I locate and install this libjpeg.8.dylib file in my Mac?
