This isn't true, you can run fc9 rpms on fc8 and you can run fc8 rpms on
fc9.
I have done both, just as long as the dependencies are met.

It seems to me that for starters the sugar rpm is broken.
It doesn't require python-json which is imported by activity.py.
And the terminal activity won't run without it.

So if sugar isn't checking for what it needs, how is any activity going to?
