Arduino Pro IDE compile error

I have Arduino Pro IDE v0.0.5-alpha.preview installed on my MacBook. I installed the boards I need in the board manager. But when I go to verify a sketch I get this error “compilation error: Error: 2 UNKNOWN: fork/exec /bin/avr-g++: no such file or directory” Does anyone know how to fix this on Arduino Pro IDE. Oh and I do still have the regular Arduino IDE installed as well.

I agree that using alpha software is generally not a good idea. However I’m looking for help to make it work.
