AttributeError: 'Shell' object has no attribute 'dot'

I'm trying to run this command, and I'm getting this exception:

$ python tracegraph.py -t MX --graph png --output booking.png --skip . --skip com. booking.com

These are the libraries I have installed:

dnspython==1.15.0
whelk==2.7

Hi David,

I run into exactly the same issue, have you fixed the issue?

Many thanks.

You'll need to install graphviz for this to work.

Hi Dennis,

Does the script support private domain?

I have a patch that makes the error message more friendly, see #6.
