I just installed RVM and after a little bit of difficulty I got it working.
But I now have a problem.
I can still run scripts and individual commands on the command line, but I
can't get an interactive shell. The jruby command just waits forever. When I
run jirb, a ton of processes called java appear, and although they use a
lot of CPU power and memory they don't appear to accomplish anything.
When I asked for help elsewhere, it was suggested that I run
jruby -rirb -e IRB.start
But that spawned about 20 java processes that consumed all the memory on my
system, and I had to abort the process.
When I run the command jruby -v I get

1.6.0_30-b30 [linux-amd64]
And running rvm info yields:
