Ao executar o Jekyll estava recebendo o seguinte erro:

/Users/glauco/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require': iconv will be deprecated in the future, use String#encode instead.

Depois de passar algum tempo pesquisando, descobri que exportar o locale correto era o suficiente para resolver o problema:

export LC_CTYPE=en_US.UTF-8
export LANG=en_US.UTF-8
