php-mode package reports a missing file when installing

[Maitre Bart]

Binary package hint: php-mode

Installing the php-mode package (0.1-1ubuntu1) causes the following error to be reported at the end of the installation:

Errors were encountered while processing:
php-mode
E: Sub-process /usr/bin/dpkg returned an error code (1)
A package failed to install. Trying to recover:

I'm using Ubuntu 8.04.2 (release 8.04)

I went on the forum first (please, have a look at http://ubuntuforums.org/showthread.php?t=1115906).
The error still occurs even if I install the emacs21 or emacs22 meta-packages.

The problem is (an annoyance, should I say) that it's all like the php-mode package still remains in the synaptic's installation queue.
So for any other package I try to install thereafter, synaptic will attempt to complete the php-mode every time, but it never succeeds.

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.
