How to install OpenCV on OS X Lion using brew

I am trying to install opencv libraries using brew. I tried:

sudo brew install opencv

      

        
        
        
      

    

this is the result:

user$ sudo brew install opencv
sudo: /var/db/sudo writable by non-owner (040777), should be mode 0700

WARNING: Improper use of the sudo command could lead to data loss
or the deletion of important system files. Please double-check your
typing when using sudo. Type "man sudo" for more information.

To proceed, enter your password, or type Ctrl-C to abort.
