Compile python dolfin with cgal

Question

I wanted to install fenics and used the suggested commands

sudo add-apt-repository ppa:fenics-packages/fenics
sudo apt-get update
sudo apt-get install fenics
sudo apt-get dist-upgrade 

During the installation I got the error:

Processing triggers for python-support (1.0.15) ...
/usr/lib/pymodules/python2.7/scitools/pyreport/main.py:268: SyntaxWarning: import * 
only allowed at module level
  def __call__(self, name, globals=None, locals=None, fromlist=None,
/usr/lib/pymodules/python2.7/scitools/pyreport/main.py:285: SyntaxWarning: import * 
only allowed at module level
  def __call__(self, name, globals=None, locals=None,

When conducting the following commands in a python shell:

from dolfin import*
has_cgal()

I get

False

I guess I have to compile Dolfin together with CGAL but how? Any ideas?
