Comment (by josephsacco):

 Here are some things to explore:

 (1) The current GitHub repository version of ImageMagick 7.1.0 builds
 within a MacPorts environment with requisite dependencies installed [see
 Install-mac.txt file in the source distribution]  and passes all tests
 {{{
 ============================================================================
 Testsuite summary for ImageMagick 7.1.0-21
 ============================================================================
 # TOTAL: 86
 # PASS:  86
 # SKIP:  0
 # XFAIL: 0
 # FAIL:  0
 # XPASS: 0
 # ERROR: 0
 }}}


 (2) "configure" supports the modification of program names, which will
 allow multiple versions of ImageMagick to co-exist
 {{{
 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
 }}}

 (3) Create and ImageMagick_select to select the preferred default version

 (4) Identify all MacPorts apps that depend upon ImageMagick and begin
 testing with ImageMagick 7.x
