 > I see this in the log:
 > {{{
 > :info:build /usr/local/include/eigen3/Eigen/Array:8:4: error: #error The
 Eigen/Array header does no longer exist in Eigen3. All that functionality
 has moved to Eigen/Core.
 > }}}
 > That means you have a header in /usr/local that is interfering. Because
 of this common problem, we don't support using MacPorts while there is
 anything in /usr/local. Please move /usr/local aside (for example by
 renaming it to /usr/local-off), then clean opencv again and try installing
 it again.

 Worked for me also!! THANKS
