[ros-users] Issues with rosdep & installation path

[Tully Foote]

Shankaranand,
Installing no packages is expected.  rosdep tests whether the packages
required are installed already, and will not try to install them if they are
found.

However, the many overrides suggest that yout have set ROS_HOME to ~/ros/ros
 ROS_HOME if set should be a writable directory preferably out side of
source control which which is the default location for log files and a few
other things.  See http://www.ros.org/wiki/ROS/EnvironmentVariables#ROS_HOME

As for multiple copies of ROS installed.  They will not interfere with each
other as long as only one of them is on your ROS_PACKAGE_PATH and ROS_ROOT.
 The one in ~/ros sounds like you installed it from source.  You can use
either the binary based install or the source based install as long as you
are consistent.
