How to get opencv on electric precise (ubuntu 12.04)?

edit

Looks like the answer is to edit the vision_opencv/rosdep.yaml file to add an entry for precise, thus getting it to use the package libopencv-dev that you can install via Synaptic, etc. For example, here's part of my vision_opencv/rosdep.yaml:

opencv2.3:
  ubuntu:
    lucid:
      apt:
        packages: [libopencv2.3-dev=2.3.1+svn6514+branch23-12~lucid]
    maverick:
      apt:
        packages: [libopencv2.3-dev=2.3.1+svn6514+branch23-12~maverick]
    natty:
      apt:
        packages: [libopencv2.3-dev=2.3.1+svn6514+branch23-12~natty]
    oneiric:
      apt:
        packages: [libopencv2.3-dev=2.3.1+svn6514+branch23-12~oneiric]
    precise: 
      apt:
        packages: [libopencv-dev]
