You need to help the OS to find libboost_python.so.1.28.0 
Usually, that means putting its directory in some environment variable.
If you're running on Linux, that's called LD_LIBRARY_PATH:

    export LD_LIBRARY_PATH

That's because libboost_python is not a python module.

No, we don't have an official installation procedure (yet).

Same answer. Sorry.
