setup.zsh adds wrong path to PATH environment

[jkammerl]

After sourcing setup.zsh (I am using zsh), /opt/ros/groovy is added to the PATH environment.

PATH=/opt/ros/groovy:/usr/lib/lightdm/lightdm:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/home/kammerl/bin

However, in order to include groovy binaries, PATH should contain this:
PATH=/opt/ros/groovy/bin

This is my catkin installation from ros-shadow-fixed:

ii python-catkin-pkg 0.1.9-1 catkin package library
ii python-catkin-sphinx 0.2.1-1 ROS package library
ii ros-groovy-catkin 0.5.63-0precise-20130125-0320-+0000 Low-level build system macros and infrastructure for ROS.

One of the temp variable in setup.sh ($path) collides even if it is lower case.
