I *think* this means that it can't find the .el / .elc file that has
the '(prodide 'ipython) sexp.
Common causes:
* load-path may be set incorrectly, try something like:
(add-to-list 'load-path (expand-file-name
"~/development/python/python-mode-1.0"))
instead of your (setq load-path ....) the ~ may not be expanded
properly, which might cause this failure.
* python-mode-1.0 has sub directories that need added to the load-path.
* ipython isn't the right thing to require. Maybe you need '(require
ipython-mode)'? (I don't really think this is the issue.)
You can also run emacs under strace to see where it's looking:
$ strace -f -o emacs.strace.out emacs
Then close emacs as soon as it starts, and search emacs.strace.out for
'ipython'.
