For the command-t plugin you will need to be running a version of Vim with ruby support (like MacVim or use this Hombrew-Alt install). To check this:
vim --version | ack rubyIf you see +ruby you are all set, -ruby and you will need to recompile.
Important: Make sure to use the same ruby to install command-t as you link to your Vim install. It will not work otherwise (see here). You can check your Vim ruby by running the following command from Vim:
:ruby p RUBY_VERSIONMake sure this is the same version as your shell:
ruby -vThen run bundle exec rake make (or the alias bake make) from ~/.dotfiles/vim/bundle/command-t.
