I’m trying to install my second gem after updating to Ruby 1.9.1, and I’m having problems. First of all, I found that I couldn’t install EventMachine as it was, because it depended on Test/Unit which is apparently not bundled with Ruby as of 1.9; so I ran `sudo gem install test-unit`. Everything appeared to go smoothly. However, having cloned EventMachine from GitHub and built the gem, I get this error when trying to `gem install` the .gem file: * * * 〈Sun Feb 01 - 09:39:54〉〈elliottcable - Geoffrey〉〈~/Code/src/ eventmachine/〉〈master - ae1f407〉 âžœ gem install pkg/eventmachine-0.12.3.gem WARNING: Installing to ~/.gem since /usr/local/lib/ruby/gems/1.9.1 and /usr/local/bin aren’t both writable.
