I don't have gnome installed on here but I think something else uses
it.  Maybe it doesn't need it anymore.  I also use java but I think I
use the one from Sun that has the fetch restriction thing on it.  Just
to see if my thinking is right, should I do a equery depends <name of
each thing in the list> to make sure nothing needs it before I remove
it?  This doesn't pick up all the different versions of kernels.  I
still need to check the prune one I guess.  For that at least.

Gosh, 885 installed.  Holy molly.  That's a lot.

Thanks
