Homebrew installed: cannot update using `youtube-dl -U`

[quinncomendant]

When using brew, youtube-dl -U fails because the program tries to update /usr/local/bin/youtube-dl, which is a symlink with no write permission. The program should detect if it is installed via brew and recommend brew upgrade youtube-dl instead.

When installed with homebrew you must use homebrew for update. For outdated packages you should report to homebrew but it should be up to date.

Yeah, I discovered that. I had to run brew update before the newer version was available to brew. :-|

Still might be useful to avoid displaying the message, Make sure you are using the latest version; type youtube-dl -U to update, and instead display brew update && brew upgrade youtube-dl if it is a brew install.

When you type youtube-dl -U it will suggest using package manager. We can't determine all the package managers that exist and output corresponding message. User should know this himself.
