I am a manager of the MacPorts project, and I also want to use the buildbot master and slave as installed by MacPorts. I have no experience with virtualenv and no particular desire to learn yet another way to install software, having standardized on MacPorts some time ago. Rather, I would like to offer software in MacPorts that is functional, and that includes the buildbot master and slave.

If what we are offering in MacPorts right now is not functional, what do we need to change to make it functional? The Python infrastructure in MacPorts is not designed to accommodate multiple versions of a single Python module being installed simultaneously.

If it is really the case that buildbot, especially master, requires very specific versions of its dependencies, and cannot tolerate them being updated, how can that unfortunate situation be rectified?
