Title: Allow any rake version (including 10.x) while still avoiding the gem warning

Unfortunately the gem warning makes it hard to get (1) both a clean build and (2) really allow any version of rake to be used (especially when both rake 0.9 and 10.0 are fine). The solution is to use `~> 0` to allow any version, but not warn.
