I'm trying to dynamically load a shared library (.so) and consistently  
get "Unable to find function address." I have tried putting the  
library in a variety of locations (next to the executable, next to the  
image, next to the FFI package, etc.) and I have set the environment  
variable DYLD_LIBRARY_PATH to the location of the library. Nothing  
seems to work (although the FFI tests all pass). Any advice?
