    PythonDependency: massive refactoring.

    Closes #24842.

    bottle: only print relocations with --verbose.

Let's roll back to the commit just before that:

$ cd /usr/local
$ git reset --hard 0313168fc9287710c22e792c5581cd545ae52b59
HEAD is now at 0313168 bottle: only print relocations with --verbose.

Try again to build opencv:

$ brew install opencv

Already downloaded: /Library/Caches/Homebrew/opencv-2.4.7.1.tar.gz

==> cmake .. -DCMAKE_INSTALL_PREFIX=/usr/local/Cellar/opencv/2.4.7.1 -DCMAKE_BUILD_TYPE=None -DCMAKE_FIND_FRAMEWORK=LAST -DCMAKE_VERBOSE_MAKEFILE=O
==> make
==> make install
==> Caveats
Set PYTHONPATH if you want Python to find your site-packages:
  export PYTHONPATH=/usr/local/lib/python2.7/site-packages:$PYTHONPATH
==> Summary
🍺  /usr/local/Cellar/opencv/2.4.7.1: 217 files, 40M, built in 3.9 minute

Hooray! Now let's go back to the latest brew version: $ brew update .

thank you! :-)

Thanks, it works on my machine.
also, for who wants to use python part of OpenCV, here's another post for additional one step to setup python path

Thanks, I did brew install opencv without error, but the Python bindings weren't getting built.
Rolling back to this commit fixed my issue.
