run `bzr version` and check output, it will point you to the right 
directory with bzrlib. Also check the Python version used by bzr.

You should ensure your Trac installation runs the same Python version as 
bzr, and if needed you can add path to the directory where bzrlib 
located to PYTHONPATH environment variable. Then check with command:

python -c "import bzrlib; print bzrlib"
