Can't build on debian:stable or ubuntu:xenial in docker

[ayumi]

• Fresh docker run of debian:stable or ubuntu:xenial

• Installed curl git-core build-essential python

• Followed building.md verbatim

• Fails at anvil serve:

ayu@6179eddce8db:~/tracing-framework$ anvil serve -p 8080
Traceback (most recent call last):

    from twisted.internet import reactor
ImportError: No module named twisted.internet

pip install twisted doesn't fix this.

• Also fails anvil build.

you have to activate the virtual environment before you can actually install twisted in the correct way. I think this problem is there because an old version of twister part of the anvil-build dependencies.
