The same steps worked as expected in my Fedora 12 laptop, which is
running newer versions of twisted-* and buildbot itself. Something
must have been fixed in these versions compared to my production
builmaster/buildslave pair (it's a CentOS 3 host with some 0.7.10
buildbot and pretty ancient twisted stuff)

I'll investigate more but in the end the important thing is I'll be
able (hopefully soon) to contribute the steps I've built
