I think it is not correct to use emacs21 | emacsen in the Build-Depends-Indep field, since, AFIK, the xemacs packages provide emacsen but not the /usr/bin/emacs alternative. It would be better to use emacs21 | emacs22 | emacs-snapshot instead (the latter works, I just verified it).
The package will still FTBFS if the system administrator has manually set the emacs alternative to some not-really-Emacs-editor as zile or e3, but that's probably too weird to bother about.
