I tried to install metric_fu against my Ruby 1.9 environment, but it failed due to the problem below:

$ gem install metric_fu

...

Fetching: rcov-1.0.0.gem (100%)
Building native extensions.  This could take a while...
ERROR:  Error installing metric_fu:
        ERROR: Failed to build gem native extension.

        /Users/xxx/.rvm/rubies/ruby-1.9.2-p290/bin/ruby extconf.rb
**** Ruby 1.9 is not supported. Please switch to simplecov ****

It says "switch to simplecov", but how to do that?

UPDATE: Resoved after installing rcov 0.9.11. I found the same issue here:
