bundler: failed to load command: rake

I'm trying to install a rails 3.2.22, ruby 1.9.3 app locally. I'm using bundler 1.17.3. I've managed to get through an openssl error, and a mysql 1.9.2 error, but now I'm getting:

bundler: failed to load command: rake (/Users/{username}/.rvm/gems/ruby-1.9.3-p551/bin/rake
NoMethodError: undefined method `b' for "db:schema:load":String

I've been searching for quite some time, but I haven't hit on any results on how to fix this issue. Anyone have any ideas? Thanks.
