ruby 1.9 -- Gem is there but it says its not?

I just installed 1.9 on my 10.6 OSX, and it runs as the "ruby1.9" command.

So I'm trying to do:

sudo rake1.9 install

But it keeps telling me

Jeweler (or a dependency) not available. Install it with: gem install jeweler
rake aborted!
no such fi开发者_如何学JAVAle to load -- git

However, if I type:

gem1.9 list

The jeweler gem is clear as day right there... wtf!?! Why is it like this...? Anyone know?

It's saying the git gem/library/file isn't found:

no such file to load -- git
