I ran into an issue while installing the Command-T VIM plugin on my Ubuntu box. Once installed, I received this ever so helpful message which trying to launch VIM: 

Vim: Caught deadly signal SEGV
Vim: Finished.
Segmentation fault

If you’ve run into the problem too, chances are you’re running RVM and your default Ruby is something other than the version used by VIM. Since I installed vim through apt, it’s using the default Ruby provided by Ubuntu.

Here’s the fix:

  1. Go back into your .vim/ruby/commnd-t directory.
  2. Type: make clean
  3. Type: rvm system
  4. Type: ruby extconf.rb
  5. Type: make

That fixed it for me, hopefully it fixes it for you too.
