I've posted about this before and I feel like a real *****, but I still don't get it.

Here's the specific example: I want to modify mTasks to work more to my liking. I'm a software engineer and the changes are pretty simple, so I'm not expecting problems actually doing the development. The problem is setting up beforehand.

I checked out the code onto my (64 bit) Ubuntu desktop. But I can't run the code due to python-osso being missing. It's not in the Ubuntu repositories.

According to the PyMaemo pages, I can install python-osso by first installing scratchbox and then jumping through a bunch of hoops. I can do that, I guess, if it's required. But another page says if I only need scratchbox if I'm developing in C. Which is it?

I can't seem to find a simple, consistent set of instructions for how to get set up to do python development for the N810.
