Little problem with arduino

[system]

Hello

So i have a problem with Arduino, probably it is really stupid, but I don't get it.
I was uploading my sketch to the board but it gave me an error saying "OUTPUT was not declared in this scope"
So I opened a basic blink sketch to see if that worked, and again, the same error.

How can I solve this??

Try moving the Arduino App Icon / bundle to another directory.
