I have Squeak 4.5 All-In-One working in Kbuntu Linux after downloading, unzipping, and executing Squeak.sh   Attempting the same on a Raspberry Pi with the default OS, it downloads, unzips, and says squeak.sh is an executable file, do I want to execute?  I click execute then it does nothing.  What is needed to make it work?

I am working to hopefully get eToys video to work on Squeak 4.5 on a Pi 1 or 2, the cheapest computer I know about.  

Thanks.
