title: having trouble installing openCV using Homebrew
body: <p>I'm runing mac os x mavericks and I'm trying to install openCV using Homebrew I'm not sure how to fix it should I unistall Homebrew and python and try again if so how can I unistall them </p>
  
  <p>first I did this 
  <strong><em>ruby -e "$(curl -fsSL <a href="https://raw.githubusercontent.com/Homebrew/install/master/install" rel="nofollow">https://raw.githubusercontent.com/Homebrew/install/master/install</a>)"</em></strong> 
  then this
  <strong><em>brew tap homebrew/science</em></strong>
  which is worked cuz when I typed <strong><em>brew tap homebrew/science</em></strong> again  I got <strong><em>Warning: Already tapped!</em></strong></p>
  
  <p>but when I type <strong><em>brew info opencv</em></strong> I got this error 
  <strong><em>Error: No available formula for opencv</em></strong> 
  and when I tried brew <em>install opencv</em> it shows this </p>
  
  <pre><code>Searching formulae...
  Searching taps...
  mymac:~ user$
  </code></pre>
  
  <p>this is what I got when I run brew doctor </p>

  working fine: please don't worry and just ignore them. Thanks!
  
  Warning: Python is installed at /Library/Frameworks/Python.framework
  
  Homebrew only supports building against the System-provided Python or a
  brewed Python. In particular, Pythons installed to /Library can interfere
  with other software installs.
  
  Warning: /usr/bin occurs before /usr/local/bin
  This means that system-provided programs will be used instead of those
  provided by Homebrew. The following tools exist at both paths:
  
      2to3
      2to3-2.7
      idle
      idle2.7
      pydoc
      pydoc2.7
      python
      python-config
      python2.7
      python2.7-config
      pythonw
      pythonw2.7
      smtpd.py
      smtpd2.7.py
  
  Consider setting your PATH so that /usr/local/bin
  occurs before /usr/bin. Here is a one-liner:
      echo export PATH='/usr/local/bin:$PATH' &gt;&gt; ~/.bash_profile
  
  Warning: Your Xcode (6.0.1) is outdated
  Please update to Xcode 6.1.
