 You can also use LD_PRELOAD to preload a library so when the binary is run
the preloaded one will be used and not the one in your regular library path.
Thus forcing the use of a specific library.

  LD_PRELOAD=/path/to/library/libmythtv-0.20.so.0  mythshutdown

   for a one off execution, or you can use the following so that for the 
duration of your shell being open it would be used

  export LD_PRELOAD=/path/to/library/libmythtv-0.20.so.0
  mythshutdown
