I've been testing with my screensaver, Pastels, but I just tried with  
SillyBalls and it also failed to load.

macholib 1.1
modulegraph 0.7
altgraph 0.6.7
bdist_mpkg 0.4.2

Any others?

Console output from opening SillyBalls:

This may mean that an unexpected error has occurred, or that you do  
not have all of the dependencies for this bundle.

I've been deleting old versions from ~/Library/Screen Savers/ (which  
is where I've been installing them), which seems to get my updates  
picked up OK.

Thanks for the help!

"The real trouble with this world of ours is not that it is an  
unreasonable world, nor even that it is a reasonable one. The  
commonest kind of trouble is that it is nearly reasonable, but not  
quite. Life is not an illogicality; yet it is a trap for logicians.  
It looks just a little more mathematical and regular than it is; its  
exactitude is obvious, but its inexactitude is hidden; its wildness  
lies in wait." --G.K. Chesterton
