Arduino Uno compiling but not loading sketches

I am using a MacBook Air with OSX. I have previously had my Arduino Uno running flawlessly with a Servo Shield controlling a Dual Axis Solar Tracker.

Tonight my tracker started balking and stuttering. So I came to troubleshooting and tried everything mentioned including stripping everything connected to the board except the USB cable.

When I seems to compile properly , but when I download I get:

Arduino: 1.6.7 (Mac OS X), Board: “Arduino/Genuino Uno”

Sketch uses 450 bytes (1%) of program storage space. Maximum is 32,256 bytes.
Global variables use 9 bytes (0%) of dynamic memory, leaving 2,039 bytes for local variables. Maximum is 2,048 bytes.

Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.

This report would have more information with
“Show verbose output during compilation”
enabled in File > Preferences.

So then I enabled Verbose during compile and what I got is attached (it was too long to post in message).

It is possible that the bare wires from the resistors that join all my LDR’s linked to pins 1-3 and ground may have touched against bare metal on my base. If it is the result of a short, I can buy a new Arduino Uno.
I just hope it is not due to my lack of care to prevent a short hazard.

Thanks for your hel!p
