I can reproduce when installing in an environment in which Trac is not already installed. It seems to be due to the install_requires. Putting Trac in install_requires is not recommended. See #9800 for details.

diff --git a/setup.py b/setup.py

     package_data = {

So I guess the most logical resolution is to make sure Trac is installed in your environment. You should be able to:

$ python
Python 2.7.4 (default, Sep 26 2013, 03:20:26) 
[GCC 4.7.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import trac
>>> trac.__version__
'1.0.2dev-r0'
