" think that libraries especially mature and massive libraries, or lack thereof, is holding ruby back."
JRuby FTW.
Yes, there are downsides to sitting on the JVM, but for anything other than one-off scripts, or where start-up speed is really important, JRuby gives the best of both worlds[0]: Ruby syntax with JVM libraries.
[0] Clearly if you do not care for Ruby syntax then this is not a win. I believe, though, that JRuby is more advanced and stable than Jython. But the Jython folks are quite capable for continuing to kick ass, so that will improve.
