Ok, then first do this:
gem -v
find out what version you've got now.
Should be 1.0.0
right?
If not, go into rubygems-update-1.0.0
it is a directory.
there is a readme in there check what's in it. You might need to do  
something with stuff in there first, then run the update again...
or perhaps one of the paths was wrong in the updater? (wrong for your  
system)
You might need to set an explicit path for the updater.
You might even need to do a manual update.
None the less, the latest version should be 1.0.1
I had 6.x or 7.x before updating it myself recently.
I had Ruby 1.8.4 for a long time too.
Then recently, some gems were giving errors, so I updated things and  
everything is working better.
