Here is the output when I try to install the gem: Building native extensions. This could take a while… Successfully installed SystemTimer-1.2 1 gem installed Installing ri documentation for SystemTimer-1.2… Updating ri class cache with 6252 classes… /Users/chabgood/.gem/ruby/1.8/gems/rdoc-2.4.3/lib/rdoc/ri/driver.rb: 818: [BUG] Bus Error ruby 1.8.7 (2010-01-10 patchlevel 249) [i686-darwin9] Any idea why this is happening, on a mac? When I rake unpack the gem there is nothing in the directory.
