Why would I be getting these errors when running any of the commands
in rails (rails console/rake/etc)?

$ rails server

Looks like you are running ruby 1.9.0, 1.9.0 was a somewhat unstable
development release of ruby. The first production ready release of the
1.9 series was 1.9.1 and you should be using that if you want to run
ruby 1.9

I got everything to work in downgrading to Rails 2.3.5 (using beta
means there isn't much documentation out there and it was quite
inconvenient) and upgrading to Ruby 1.9.1. Thanks!
