Usually you'll want to use pip rather than easy_install, but I see that you 
are following the upgrade steps documented by Bitnami, so probably good to 
stick with that:
https://docs.bitnami.com/installer/apps/trac/administration/upgrade/

Your version of setuptools is very old. I would upgrade setuptools. Try:

C:\Bitnami\trac-1.0.1-3> pip install -U setuptools
