Package: xemacs21 Version: 21.4.24-12 Severity: important Files in /usr/share/emacs/site-lisp are not necessarily compatible with XEmacs. So XEmacs should not try to byte-compile them, or at least, package installation should no fail because of that.
For instance, mmm-mode is not compatible with xemacs21, so that its maintainer had to add "Conflicts: xemacs21". This is not satisfactory: a multi-user machine may have the packages emacs-gtk and xemacs21 installed because there are users who use GNU Emacs and other users who use XEmacs. In such a case, with the current situation, it is not possible to install mmm-mode for GNU Emacs users because of the conflict. This is really bad. FYI, here are the errors one obtains when installing mmm-mode if "Conflicts: xemacs21" is removed and xemacs21 is installed: [...] Setting up mmm-mode (0.5.9-2) ...
