Do you know how to fix this? I am getting the same error on my mac while installing ruby 1.9.2

Try this:

1. uninstall kgio and unicorn (all versions)
2. install kgio
3. install unicorn

This should fix. You may also need to manually delete the kgio install dir under rvm or your gem dir if you're not using rvm.

Oh ok. Thanks. But my problem is related to the xmlparser gem. I have freshly installed ruby 1.9.2 and trying to bundle install nokogiri (which uses xmlparser).
