jruby-openssl

Hai friends,
I am sending emails using the GMail mail server with TLS. I need to
install openssl for that functionality.

But whenever i try to install it using
  jruby -S gem install jruby-openssl

it is giving me error,

JRuby limited openssl loaded. gem install jruby-openssl for full
support.

ERROR: Error installing jruby-openssl:
        invalid gem format for
C:/jruby-1.4.0/lib/ruby/gems/1.8/cache/jruby-open
ssl-0.6.gem

Can you plz tell me what is the problem behind it? My internet
connection is somewhat slow.Is it because of that?

Thanks and Regards,
Veena
