When installing ruby-default an older version of Ruby is installed by default. This breaks many application that require recent versions of Ruby (>1.9). Please also note ruby1.8 will be no longer supported after june 2013.
Step to reproduce:
1) sudo gem install ./hpfog-0.0.14.gem
2) sudo gem install ./hpcloud-0.0.14.gem
3) run command : hpcloud
$ hpcloud
