But… don't sudo!
Homebrew can be used with or without sudo, but, OS X was designed to minimise sudo use, you only need it occasionally. For example, as long as your user is in the admin group, this just works:
cpan -i MP3::Info
Using sudo all the time is annoying, but far worse — it conditions you to type in your root password without thinking about it. Homebrew compliments OS X so you are unlikely to install anything that really needs to be chown:root. Let this be your last sudo for some time:
sudo chown -R `whoami` /usr/local
NOTE: If you already installed, eg. MySQL into /usr/local then the recursive chown may break it. Fixing MySQL should be as simple as:
sudo chown -R mysql:mysql /usr/local/mysql
Also 'inane blogspam' seems a bit much, no?
