Our package is a native Linux app, however, a few of us prefer the Mac so an enterprising architect got us compiling on the Mac and it's just worked all along.  Never seen any problems until now.

Don’t use DYLD_LIBRARY_PATH; it tells the OS you know better than it where libraries are located, and to look only in the paths you specify; that’s seldom what you want.

You can use DYLD_FALLBACK_LIBRARY_PATH as a stopgap measure; it tells the OS to look in the specified locations *after* all the other locations where it would normally look.

The correct long-term solution is to fix your libraries so they’re compiled with the correct -install_name parameter so that these variables aren’t needed at runtime.
