Accelerate module use cython, and is activated by default, if cython is
correctly installed. Please refer to http://www.cython.org/ about how
to install cython on your environment.
You can control the usage of accelerate module with env variable ::
PYMT_USE_ACCELERATE
If the env is set to 0, the module will be deactivated.
