* add unison

  - unison uses a wrapper script to add font-schumacher-misc to the local X font path
    if the font isn't already present; this is necessary for it to work, but not terribly
    nice ...
* lablgtk is a dependency of unison
  - handling of library dirs with ocaml is a hack so far; in principle, ocaml needs
    a general setup for library dirs like ghc
