There's only what, about 700-800 Pandora units in the world? And they're on HotFix 4 "already". Pandora is currently a moving target, so I wouldn't expect stability to be a huge feature yet - which makes keeping up problematical for any software developer. Including, I imagine, the dev behind GLBasic.
The only fixes there are, are related to wifi drivers, bluetooth drivers and so on and so on. The actual os is pretty much the same all the time.
The problem lies in the installation script there are faults in the script, causing the installation to fail. It has nothing to do with the os itself. I think Gernot has been trying real hard to get it to work. He probably created the script after registering what was needed for it.
I only ask that someone try it on a Pandora that has a freshly flashed os image on there (basically the state mine was in) and find out what are the issues with the installation script. At the end of this year there will probably be over 6000 Pandora's in the wild.
