No, it's the first one with that particular doctest in place. I just
tried it on my 2.10 tree, and it creates the exact same bug.
Since we're mentioning it, there's a known issue with the readline
build on certain platforms, which you can spot by looking at your
install.log at the section where readline gets installed. I don't know
why these would be related, and Michael Abshoff is suspicious -- which
probably means I'm wrong :) -- but if I were motivated to look, I'd
probably start there. This is trac ticket #1259. It's easy to get the
build problems to go away, but I'm not sure if it's the "right" way to
do so -- if you untar the readline package, go into src/support, and
look at shobj-conf. If you edit line 145 to say:
darwin[89]*)
and line 174 to start with
darwin[789]*)
then it builds with no errors. However, if you look at what you're
doing, you're basically just telling the builder to use the same
options for 10.5 (which is what I assume Darwin9 is?) as it uses on
Darwin 8. I have absolutely no idea whether or not that's a wise idea.
Once one does this, you could try rebuilding all of Sage with the new
readline package, and seeing if you get the same troubles.
