The Emacs site-init file that comes with ipython causes significant overhead at Emacs startup: - It contains an unconditional "require" statement that will load ipython.el - ipython.el will then load the (large) common-lisp library, plus other files It would be desirable to postpone loading of ipython.el until it is first needed, which is after python-mode is loaded. For further details, see <http://overlays.gentoo.org/proj/emacs/wiki/sitefile%20problems>. A new site-init file will be attached.
Created attachment 134201 [details] 62ipython-gentoo.el New Emacs site-init file, goes to $FILESDIR.
ipython-0.8.1-r1 fixes this, thanks for reporting :)
