pgAdmin4 Bug fix or my Fault ?

Hi,
I am using Debian Jessie and install pgAdmin4 Required modules.
after I clone pgAdmin4 from
http://git.postgresql.org/gitweb/?p=pgadmin4.git;a=summary ,

First of, ıf I want run setup.py, I must fix bug .
after I want run pgadmin4.py, I must fix gravatar import line.

In this case,
There are really bugs?
or
is it my fault ?Thank you.
