JAVA problem?

Started getting error when attempting to go back to an earlier sketch to resolve my ABL issues. I now am getting the following error/ Never had this before, and not sure where to look for a solution or sketch change.

Arduino: 1.8.5 (Mac OS X), Board: "Sanguino, ATmega1284 or ATmega1284P (16 MHz)"

Sketch uses 120910 bytes (92%) of program storage space. Maximum is 130048 bytes.

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

Appreciate an interpretation or any help. Thanks in advance for looking at this.

"Cannot run program "/Users/noelkuck1/Library/Arduino15/packages/arduino/tools/avrdude/6.3.0-arduino9/bin/avrdude": error=2, No such file or directory"

fairly clear what the issue is...
