Capistrano not deploying with El Capitan Update?

[klarsendesign]

Hi there!
Been using Capistrano to deploy my websites for months now. I updated to El Capitan over the weekend and now get the error:
bundler: command not found: cap
Install missing gem executables with bundle install

So I check the bundles & run bundle install, but their all there already:

Using rake 10.3.2
Using i18n 0.6.9
Using colorize 0.7.3
Using net-ssh 2.9.1
Using net-scp 1.2.1
Using sshkit 1.5.1
Using capistrano 3.2.1
Using capistrano-bower 1.1.0
Using capistrano-composer 0.0.4
Using capistrano-npm 1.0.1
Using bundler 1.10.6
Bundle complete! 4 Gemfile dependencies, 11 gems now installed.
Use `bundle show [gemname]` to see where a bundled gem is installed.

Anyways, it was working fine before El Capitan. So I'm not sure why the bundler cap cannot be found. Any help would be greatly appreciated as this has put a hold on all my work.
