Comment (by josephsacco):

 I can almost see how to make this work. The problem is ImageMagick uses
 pkgconfig. This can be seen by running {{{port contents ImageMagick}}}.
 * The libraries are uniquely named
 * The "etc" files live in their own directory
 * The "include" files live in their own directory
 * The "doc" files live in their own directory
 * The program file names in "bin" can be made unique by specifying a
 {{{configure}}} argument:
 {{{
 Program names:
   --program-prefix=PREFIX            prepend PREFIX to installed program
 names
   --program-suffix=SUFFIX            append SUFFIX to installed program
 names
   --program-transform-name=PROGRAM   run sed PROGRAM on installed program
 names
 }}}

 As it stands,  pkgconfig files are created  as shown:
 {{{
 ImageMagick++-6.Q16.pc  Magick++-6.Q16.pc       MagickWand-6.Q16.pc
 ImageMagick++.pc        Magick++.pc             MagickWand.pc
 ImageMagick-6.Q16.pc    MagickCore-6.Q16.pc
 ImageMagick.pc          MagickCore.pc
 }}}

 The files named "fileName-6.Q16.pc" are copies[rather than hard links] of
 the files named "fileName.pc" [who knows why].

 What to do?

 If you wanted only one version to be "the" version of ImageMagick at any
 given time.  a {{{select_ImageMagick}}} port with its link magic would
 solve the problem.

 Just some thoughts...
