Tip... the word siscont displayed in the traceback report, is the name of the project environment (folder)

Until you find a solution, here is a possible work-around: I guess the reason for the failing install will be similar to what happens with Trac 0.10 and TracDownloaderPlugin install - a dependency cannot be resolved. PyCaptcha? I could only find for up to Python 2.4! So if you can live without the Captcha (and have it disabled), you may just remove it from the dependencies in the setup.py script - simply remove the lines 

  """install_requires = ['PyCAPTCHA >= 0.4',
                      'PIL >= 1.1.5'],"""

The dependency for PIL you already have provided, according to your post :)

I cannot guarantee that this works for you - though it worked for me, the error message looked a bit different...

See #3338. Mitigates the problem so pages render. Plugin still broken, however.
