Comment 1 for bug 359695

Quick googling suggests that installing the cedet-common package might provide this file for you, but that's obviously just a quick and dirty workaround.

Installing emacs21 or emacs22-specific stuff will generally put it in locations where Xemacs21 will not see it. It's not clear to me why the guy on the forum believed that emacs22-common would provide this file, anyways. http://packages.ubuntu.com/search?searchon=contents&keywords=ezimage.el&mode=exactfilename&suite=intrepid&arch=any says it's only in cedet-common.

It's not obvious to me how this ought to be fixed; should emacs-extra depend on gnumacsen | cedet-common or what? Actually perhaps it could unconditionally depend on cedet-common I suppose, at least as a quick fix.
