Teamocil throwing error "show-window-options: illegal option -- v"

[luisthethird]

when running teamocil (1.4.2) in a tmux (1.6) window on "MacOSX Yosemite" using the following command "teamocil Keyservers-all"
The following errors appear:

show-window-options: illegal option -- v
usage: show-window-options [-g] [-t target-window]
new-window: illegal option -- c
usage: new-window [-adk] [-n window-name] [-t target-window] [command]

This is happening when trying to use the following yaml file (Keyservers-all.yml)

windows:

• name: Keyservers-All
  root: ~/
  layout: tiled
  options:
  synchronize-panes: true
  panes:
  • commands:
    • ssh ubuntu@keyserver$MIA_URL
      focus: true
  • commands:
    • ssh ubuntu@keyserver$ATL_URL
  • commands:
    • ssh ubuntu@keyserver$PHX_URL
  • commands:
    • ssh ubuntu@keyserver$TOR_URL

Additional Details:
tmux was installed through "brew install"
