Error compiling for board Arduino/Genuino Mega or Mega 2560

[jonawald]

I just did an up date to Arduino and got this message. I have used this computer and this arduino a few times before without this issue.

Arduino: 1.6.8 (Mac OS X), Board: "Arduino/Genuino Mega or Mega 2560, ATmega2560 (Mega 2560)"

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

It doesn't look like you're using the latest version of Arduino... Are you sure you're on the latest version?
