Comment(by vishketan@…):

 IMHO the clean thing is to ensure that an emacs meta-package is installed
 when one of emacs, emacs22, emacs-snapshot, emacs-app, or emacs-app-devel
 is installed. This meta package will write this subdirs.el file and set
 links to the appropriate emacs binaries. Once this is done other emacs
 goodies (e.g. org-mode, cedet, ecb etc) must be modified to depend on this
 meta-package rather than on individual emacs instances as is currently
 being done. IIRC this is the way distributions like debian do things.
