GAE dev_appserver "No module named lxml"

Question

It seems lxml is not available for me in dev_appserver. I have test project is import lxml line built with windows python sdk 1.6.6. "No module named lxml". I assume something with installed version of python, but I have Python 2.7.

import webapp2
import lxml

class MainHandler(webapp2.RequestHandler):
    def get(self):
        self.response.out.write('Hello world!')

app = webapp2.WSGIApplication([('/', MainHandler)],
                              debug=True)

===

application: teslxml
version: 1
runtime: python27
api_version: 1
threadsafe: yes

handlers:
- url: /favicon\.ico
  static_files: favicon.ico
  upload: favicon\.ico

- url: .*
  script: main.app

libraries:

Update: This isn't true anymore, lxml is now shipped out of the box. https://cloud.google.com/appengine/docs/standard/python/tools/built-in-libraries-27

lxml doesn't come out of the box with Google App Engine, you need to install it.
