 Unable to build opencv 3.3 with the contrib variant.  This is OSX Sierra.

 Commands I ran are:
 sudo port install opencv +python27 (works)
 sudo port install opencv +python27+contrib (fails)

 Error is:
 Log error is: Failed to find Ceres - Found Eigen dependency, but the
 version of Eigen found (3.3.4) does not exactly match the version of Eigen
 Ceres was compiled with (3.2.4).
