emacs21 held hostage to installing other packages

[Charles Blair <c-blair@uiuc.edu>]

   I recently installed the testing (etch) incarnation of debian,
and have added emacs (emacs21).  I would like to add gnumeric
and a number of other packages, but aptitude warns me that, to
do so, I have to downgrade some things (libc6 is one), and that
this will delete emacs21.
