[Aldo]

Scratch is a blocks programming language for kids available at: http://scratch.mit.edu

Platform? ARM7 (A20) - Banana Pi
OS? Raspbian (Debian Wheezy)

Errors when loading the blocks editor (the first erros repeat for a long time - I have truncated them - at the end tehere are a few original errors):
