Laravel Setup: Can't install Monolog

Question

I just tried to install a fresh instance of Laravel as described in the docs ( http://laravel.com/docs/quick#installation - "Via Composer"). Got this error from Composer:

...

Uhm, what to do now? Tried to post it on the official forums but that wasn't possible due to an error there (forums are based on Laravel... yeah that's Karma!).
