Comment(by blb at macports.org):

 It will miss dependencies that are only activated in variants, so a brute-
 force grep against all Portfiles is the best method here.  The following
 were found and not in the above list:

  - aqua/pixen - just in a comment
  - lang/pike - +image variant
  - x11/xplanet - +gif variant
