If you encounter a problem with running Python [python] scripts on a “bare” Blender Player [blender], make sure that both PYTHONHOME and PYTHONPATH are set correctly to match your needs. You can also use native Blender python with a simple shell script:

#!/bin/sh
export PYTHONHOME="/path/to/blender/python/"
export PYTHONPATH=$PYTHONHOME"/bin"
/path/to/your/blenderplayer $@
