Checking for existence of programs in scriplets is a bad hack which
might hide real problems and the scriplets are getting more complicated
by this.

Placing scriplets and related files into separate subpackages is a much
cleaner solution.

check with the shell builtin 'type $prog' is more portable and does not
require the external 'which' program.
