Specs don't pass because spec-supplied version is too low

[robheittman]

The compatibility check requires a patchlevel>14, but the spec doesn't supply that; it supplies the minimum compatible version. Something like this works:

diff --git a/spec/server_spec.rb b/spec/server_spec.rb
index 72895ef..89036d2 100644
--- a/spec/server_spec.rb
