What PATH makes Squeak work on Raspberry Pi?

Amazingly I'm sending this email from my Pi.

I made this squeak.sh file for my Pi desktop.  Double click produces nothing after the request to execute pop-up menu. Entering each line in a Terminal on the last statement closes the terminal.

Suggestions please?  Thanks. 

PATH=/home/pi/Squeak-4.5-All-In-One/Squeak-4.5-All-in-One.app/Contents/

VM="/home/pi/Squeak-4.5-All-In-One/Squeak-4.5-All-in-One.app/Contents/LinuxAndWindows/Linux-i686/bin/squeak"

IMAGE="/home/pi/Squeak-4.5-All-In-One/Squeak-4.5-All-in-One.app/Contents/Resources/Squeak4.5-13680.image"

exec "$VM" "$IMAGE"
