Rubygems - 404 Error for gems.datamapper.org/yaml

[Old Echo]

Hi everyone,
I'm at my wits end here. I've been trying to install a gem all day, but
Rubygems won't let me because it keeps crashing while trying to update
gem metadata for some Datamapper gems.

I had originally added the gems.datamapper.org repo to my sources, but
now I can't remove it, because...doh...Rubygems always wants to update
metadata BEFORE running any command.

I'm on Mac OSX Leopard using the normal Ruby 1.8.6 that came with the
box.

Below is a transcript of my trials and tribulations:

ca1-osx-l214:Library kodama$ gem install trollop

ca1-osx-l214:Library kodama$ echo Oh noes

Can anyone point me in the right direction on this?

Thank you very much,
kodama
