Comment (by fmw42):

 I tried again today. I found that I could not import cv2 into python and
 got the following error:

 {{{
 python3.5
 Python 3.5.3 (default, Feb 10 2017, 16:04:07)
 [GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin
 Type "help", "copyright", "credits" or "license" for more information.
 >>> import cv2
 Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
 ImportError:

 /opt/local/lib/libwebp.6.dylib
   Referenced from: /opt/local/lib/libopencv_imgcodecs.3.1.dylib
   Reason: image not found
 }}}

 which made me think that I needed to reinstall webp. So I tried that but
 got further errors.

 {{{
 Error: Requested variants "+contrib+python35" do not match those the build
 was started with: "".
 Error: Please use the same variants again, or run 'port clean opencv'
 first to remove the existing partially completed build.
 Error: rev-upgrade failed: Error rebuilding opencv
 }}}

 which seems to have trouble with adding +contrib+python35 to opencv.

 So I tried:

 {{{
 sudo port clean opencv
 }}}

 and then
 {{{
 sudo port install opencv +contrib+python35
 }}}

 But it failed at a different spot this time.

 I am attaching my session log and the listing from
 /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_graphics_opencv/opencv/main.log
 for details.
