I'm trying to install jruby on a DreamPlug (an ARM-based platform). Unfortunately without success.
First I'm trying to install using rbenv and openjdk 7, this is the result:
Downloading http://jruby.org.s3.amazonaws.com/downloads/1.7.0.RC2/jruby-bin-1.7.0.RC2.tar.gz...

Next I tried to install using rbenv and openjdk 6, this is the result:

Going a little further I manually downloaded jruby and I can actually run the jruby command which says:
jruby 1.7.0.RC2 (1.9.3p203) 2012-10-09 142cc7b on OpenJDK Zero VM 1.6.0_18-b18 [linux-arm]
It's the same in rbenv when checking - I can run the jruby command but cannot install rubygems (such as bundler), that gets me this on jdk 6:
gem install bundler

Didn't try jdk 7 here but I assume I would get the same error as with rbenv since the above is the same as with rbenv on jdk 6.
So I wondered if it had something to do with jruby 1.7 - trying to install jruby 1.6.8 (jdk 6) gives me this:
ArgumentError: Illformed requirement [">= 0"]

So basically the same error I guess.
I've tried switching from Debian Wheezy to Ubuntu but I get the same errors there... so I'm wondering if it's related to the ARM-platform and if there is a
workaround or a way to make JRuby run on this platform? The cpu is an ARMv5 called Feroceon so it's not really the latest and greatest.
