[IPython-user] readline egg on leopard

I'm sorry to hear about your problems and will help you as far as I
can to get this sorted out...

First off, if you are using ipython 0.8.3 or later (if I remember
correctly), readline might not actually be necessary. The support for
the builtin libedit library on Leopard improved to such an extent that
you will probably not miss readline at all (tab completion, up arrow
and such all work). My first suggestion is therefore to forget you
ever heard about readline :-) Just try out ipython and see if you miss
some functionality, and then come back to readline if it is really

On the other hand, I am curious why your installation did not work, so
here goes...

These instructions should be replaced by:

sudo easy_install readline

Unfortunately I do not have write access to the wiki, so someone else
(Barry?) should please update it.

No, all should still be fine, as it appears that nothing was
installed. I do not yet understand why the installation would fail, so
I will try it out on my Leopard system tomorrow.

Good luck!
