I believe this is an error cause by two gems having different dependencies on prawn. So the first one to load depends on prawn 0.11.1 and then the second one tries to load an older version but can't because the newer version has already loaded. This is the type of problem Bundler was designed to solve.
However, since it looks like you're just trying to get this to run, you could just uninstall the newest version of prawn and there's a good chance things will work out. If not, you'll have to go version hunting for compatible gems or retrofit the project to use Bundler.
