Has anyone seen this: ?? No jgem command works at all?? Though jruby -S gem list does work. I'm using jruby 1.3.1 and Sun Java6 jre

root@test:/usr/local: jgem --version  
1.3.3  

root@test:/usr/local: jgem update --system  
JRuby limited openssl loaded. gem install jruby-openssl for full support.
