Error on first run: 'require': no such file to load -- rubygems

[astrieanna]

This is the error I get when I run xiki:

$ xiki
/usr/local/google/home/lhanson/src/xiki/bin/xiki:20:in `require': no such file to load -- rubygems (LoadError)
    from /usr/local/google/home/lhanson/src/xiki/bin/xiki:20
    from /usr/bin/xiki:2:in `load'
    from /usr/bin/xiki:2

And the line it errors on:

require 'rubygems'

I followed the 'github' install instructions; I'm on Linux. I don't use ruby, so I'm not really sure what to do to get rubygems.

Sounds like you're using different versions of ruby?

If you're using ubuntu and installed ruby 1.9.3 you should check that /usr/bin/ruby and /use/bin/gem are pointing to the correct version of ruby
