    Wrap your program in a shell script:

    #!/bin/sh
    
    PROGRAM_DIRECTORY="`dirname "$0"`"
    export LD_LIBRARY_PATH="$PROGRAM_DIRECTORY"
    
    "$PROGRAM_DIRECTORY/program_executable" "$@"
    

    If you run this script (instead of your executable) your program will link just fine.

    You need $ORIGIN in your RPATH, via an appropriate option to ld or other Darwin tool. See this and this.

    Remember that the $ has to really end up in the path, so you need to quote or escape it in the link command line.

    Update: You can see what the linker actually put into your executable with

    readelf -d /path/to/exe | grep RPATH
    

    Here is what the output should look like:

     0x0000000f (RPATH)              Library rpath: [$ORIGIN]
