Comment(by chris at behanna.org):

 Replying to [comment:9 chris@…]:

 A slightly better version, IMHO, as it points out that the problem stems
 back to a malformed Portfile:

 {{{

 +               }
         } else {
                 # This is old Images format
 }}}

 The problem was an extra newline in the Portfile.  There's no way I could
 have figured that out from the original error message.
