Wow i'm soooooooooo close!

This is the closest i have got to getting a program working! - i know i have whinged in the past - as i used to do VB programming, so like it all in one place, on a plate so to speak - but this seems almost as good!
Well until i missed something most likely.

Getting a trackback error
ImportError: No module named PyQt4

This happens when i run my demo hello world file.

I'm assuming i need to install something extra on my n900? (I'm guessing an apt-get thingymebob-doodaaa?!?)

Have tried googling, but they all point at me not having something, and they all seem to be linux desktopy related, not sure what the fix would be on my n900. (I know they are similar, but best to ask to make sure!) :S

Must say i can run it on my pc, so not the same error as above
