Ah, OK, thanks. Since grep wasn't showing any such code coming from
us, I got confused.

Well :) A few weeks ago I had another run-in with that thing that
only reinforced my feelings that in certain environments (unix,
non-root, non-default location installations), that stuff is just not
really ready for prime time. I know a lot of people like it
(including you, Brian, R. Kern and many others whose judgment I
greatly respect). But it seems every time I try to use it, I manage
to find a way in which it breaks in incomprehensibly stupid ways.
After three or four of those, spread over several years, I've lost
patience with that thing.
One day we may even start using it in our core (I know Brian wants to)
but I'm holding for as long as we possibly can, in the hopes that
others will hit the same problems and will have the patience to get
them fixed first.
Obviously we'll continue to *support* it, I just want to hold on
*depending* on it until absolutely necessary.
