Maybe just try brew install cmake alone? Cannot resume. Not sure, that sounds like either a curl or Homebrew error, neither of which I know a lot about. Did you run brew doctor after installing Homebrew? Hi, I am following your steps to install OpenCV and it appears that the homebrew installer has moved. They supply the correct command when installing but thought you may want to change it on the post.
Thanks a lot Jeffrey. Just remember to force your scripts to run with Python 2.
Thanks again. Hmm, not sure.

Installing OpenCV 2.4.9 on Mac OSX with Python Support
I have the impression that brew install the Python OpenCV? This post suggests that the base OpenCV gets installed regardless, it then is bound to Python, so I think it might work. Please let me know if it does! Any suggestion? OpenCV is a computer vision library used extensively by people in the computer vision field. Until a couple of years ago, OpenCV was a bit hacky and the usage was not very straightforward. But determined efforts by multiple companies finally standardized the process and now it is nice and clean. Computer vision algorithms are computationally intensive, requiring lot of processing power to run in real time.
Before OpenCV came along, the efforts were very fragmented and repetitive, and there was no standard library as such. Hence Intel decided to do something about it and came up with OpenCV. The advantage of OpenCV is that the algorithms are highly optimized and the library is available on almost all the popular platforms.
I have outlined the procedure below to get OpenCV up and running on your Mac. We are now ready to install OpenCV. Download the latest version of OpenCV from here.
