Brian,
I finally got Homebrew working with only OpenCV 2.3.1 in it. The rest of my needs are satisfied with Macports. I changed William's opencv.rb formula so that it doesn't have any depends in it, shown below:
require 'formula'
class Opencv < Formula
version "2.3.1"
md5 '827c9f8aa14384c531c73aa165f9b777'
def install
makefiles = "cmake . "
system makefiles
system "make"
system "make install"
end
def caveats; <<-EOS.undent
The OpenCV Python module will not work until you edit your PYTHONPATH like so:
export PYTHONPATH="#{HOMEBREW_PREFIX}/lib/python2.7/site-packages/:$PYTHONPATH"
To make this permanent, put it in your shell's profile (e.g. ~/.profile).
EOS
end
end
It compiles and installs fine. Later I will play with changing options (tbb, eigen, ffmpeg, etc), but this appears to compile most of what I need (python 2.7, QT, etc).
My problem now is, when I run some of my code that uses OpenCV, it crashes with "terminate called throwing an exceptionAbort trap: 6" and I have no idea what is going on. The really weird thing is when I switch back to my Diamondback ROS, using this same code (just recompiling to ensure it is using this Homebrew OpenCV) no crash, so I am thinking it is not Homebrew OpenCV but something else.

I don't like installing source code I can't easily remove. That is why I put up with macports.
hi Kevin,
That's a fair point. But it's also an indictment of entire source
rosdep approach to pulling in third-party stuff. Can you suggest an
alternative?
We need a way to install code that isn't available (or at least isn't
available at the needed version, or in the needed configuration) from
an OS's package manager.
