This script that sets the LD_LIBRARY_PATH -- does it use 'export'?  If
you don't export the environment variable, then the parent wouldn't get
set (if I understand correctly).  This would probably cause what you are
seeing...

Change:
  LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/path/to/libs 
To:
  export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/path/to/libs
