If you are running 64-bit applications, you may need to customize your LD_LIBRARY_PATH environment variable as follows:
Set the new environment variable, LD_LIBRARY_PATH_64, like LD_LIBRARY_PATH, except that it can only be referenced by 64-bit applications.
Set the LD_LIBRARY_PATH variable to allow applications to reference a combination of both 32-bit and 64-bit libraries.
