I'm pretty sure that the python3-modules package is included by default 
when python is installed (on master)
if you wont be using master then yes, install python3-modules

The generate-manifest-3.5 script is no longer used (again, on master),
there is a new one called create-manifest where you can add more granularity
to the python build, but in this case I don't believe you need it.
