Comment 3 for bug 438469

Method 1 is not viable since the dbus configs need to be installed before tcm can be used.

Using method 3 requires that pygobject be installed so pygtk will install in the virtualenv (so I can import gtk). pygobject installation isn't supported using distutils, so it doesn't appear to be possible with zc.

method 2 requires some code changes to properly reference testing code instead of global code.

How exactly are you developing your code?
