It probably is. I've heard concerns that people want to avoid suggesting
manual uninstalls and having to download the setup scripts. But it seems
simple enough to me. (What would I know, I just run virtualenv and leave it
at that :-))

Glad it worked in the end, anyway, and sorry if my instructions made it
harder than it needed to be.

As regards distribute, I suspect that the reason you hit issues is that if
you have a setuptools that's older than 0.7 (or whatever the first merged
version was) then an upgrade can end up jumping through some hoops and
going through a "dummy" distribute version that's there to handle the
fork/re-merge somehow. I honestly don't know how it all works, I'm just
going off what I saw on some of the discussions on pypa-dev at the time. It
all sounded very clever to me, but a bit fragile. I'm a simple soul, and
prefer to just wipe it out and reinstall, so I zoned out after a while:-) I
doubt the details matter to you now, though...
