If you install nativesdk-python-modules into your SDK, you will get
python *and* all its modules installed. If you just install the python
core, you get a cut down python and need to install the modules you
need.

The python SDK has been tested and used in a number of scenarios. Where
a full set of modules is needed, nativesdk-python-modules gets installed
and everyone is happy. If there is some problem with
nativesdk-python-modules, please let us know.

Cheers,
