For anyone who is stuck on this, I finally got it working by following these instructions as stated earlier:
http://community.wd.com/t5/My-Book-Live/GUIDE-Installing-CrashPlan-for-MBL-Cloud-backup/m-p/561614/highlight/true#M21307 . Then I found an armv7l (armhf) compiled version of libjtux.so here: https://github.com/downloads/swenson/jtux/libjtux.so which I stumbled upon from the comments section of this raspberry pi / crashplan tutorial:
http://www.jonrogers.co.uk/2012/05/crashplan-on-the-raspberry-pi/ . That Jon Rogers link also has some info on changing out Java to increase the performance of crashplan (apparently significantly).
So I have it working. If anyone has questions on what I did, please reply.
