[ros-users] ROS in MacOSX (just concerns)

Well, homebrew is not going to use macports libraries to satisfy
dependencies.  If you have the dependencies for opencv, tab, jasper, tiff,
etc.., installed through macports then just install opencv with homebrew
without dependencies (brew install --ignore-dependencies opencv).  This will
prevent multiple dependencies from being installed.

Also, building opencv manually is still an option.

This is one of the general draw backs to using homebrew, is that it doesn't
mesh well with macports and loads of people already use macports for other
things.  I have yet to see a good fix for this other than just using one or
the other.

Thanks,
