I'm not entirely sure what this means, but it sounds like yes, you
should reinstall buildbot.  That really should mean just running
'python setup.py install' from a clean checkout/tarball - you won't
need to re-create the master.  But back it up just in case :)

If you're adding your own code for purposes of your buildbot install,
you should be adding it in files that are somewhere else in the python
path.  If it's short, you can just add the new classes directly in
master.cfg.  You shouldn't modify buildbot files directly, as that
will make upgrades hard.

On hte other hand, if you're fixing our broken code in preparation to
send me a patch, then have at it!  It's usually faster to just edit
the files under the python install, rather than running setup.py
install.  Also, consider using virtualenv for this purpose (and
setup.py develop).
