Problems with openssl support

I am trying to build rack-oauth2 for Debian and I am getting the following error.

Failures:

  1) Rack::OAuth2::Client#access_token! *args handling client authentication method when jwt_bearer auth method specified when private_key is given when EC key should be JWT bearer client assertion w/ auto-generated ES256-signed JWT assertion
     Failure/Error: private_key: OpenSSL::PKey::EC.new('prime256v1').generate_key,
