I think Apple tweaked something with the update to 10.5.1
Can you point me to the bug that I filed? I'll take another look.

I suspect that something isn't getting bound correctly in .editrc -- I
can probably deal with this in an ipython profile but not sure. Again,
if I can understand what "multi-line history" means maybe I can be
more intelligent. Looking at that bug report may remind me.

Readline is easy to compile on Leopard; I use MacPorts to build a
Python 2.5.1 with GNU readline. There are a number of dependencies,
mostly internationalization stuff, if I recall correctly; I have all
that solved via MacPorts. I can provide these port files, or a binary
installer for a Python 2.5.1 with readline, if you like.
I see a mention of dtrace support in Apple's Python. Hmm. I don't know
that the binary needs to do anything special to provide dtrace -- I
don't think you need to compile in any "hooks", that's the whole point
of dtrace. In any event I'll take a look at Apple's source, if any,
and see if we can't get a Leopard Python/readline set up.
But I have a strong preference for using the system Python in Leopard,
so I'd like to solve the libedit readline issues if possible.
