more; invoking it via Pcl-CVS causes the frame to split into two
windows, as expected, but I get a beep and the little Ediff control
window (frame?) doesn't pop up like it used to. I get an error about
a variable "top-gutter".
I suspect that this version of Ediff isn't compatible with Xemacs
21.1.14. If that's the case, then why didn't XEmacs spot this when I
upgraded my packages using the automatic package management tools?
It seems a bit silly that it detected the upgrade, but didn't notice
that it wouldn't actually work with itself.
How do I make it work? I will not upgrade to XEmacs 21.4.* until the
font bugs have been fixed. (Some of my fonts were still appearing
far too large when I tried 21.4.6 a couple of weeks ago.)
It looks like you're right - ediff now expects gutter support.
Unfortunately, the package system does not have a sophisticated
requirements capability built in.
I or someone else on the xemacs-beta list will have a look at this
soon, but for the time being, you can workaround the problem by not
using a separate frame for the ediff-control buffer:
(setq ediff-window-setup-function 'ediff-setup-windows-plain)
