Rosinstall fails after installing pkg-config (Homebrew electric mac 10.6.8) [closed]

edit

Hello Community,

I'm trying to install the Ros bare bones package to my Mac OSX 10.6.8 MacPro Laptop using the instructions from the electric OSX Homebrew Installation page. After several starts and stops rosinstall reports a successful installation of pkg-config then starts rosmake which fails with this:

/usr/local/Cellar/pkg-config/0.25: 9 files, 220K, built in 26 seconds successfully installed pkg-config [ rosmake ] rosdep successfully installed all system dependencies
[ rosmake ] Starting >>> tools/rospack

[rosmake-0] Starting >>> std_msgs [ make ]
[ rosmake ] All 34 linesosparam: 1.7 sec ] [ std_msgs: 1.7 sec ] [ 2 Active 4/67 Complete ]

later, after starting cmake, rosbuild reports:

*[rosbuild] Building package std_msgs CMake Error at /Users/christianjara/ros/ros/core/rosbuild/private.cmake:110 (message): [rosbuild] rospack found package "std_msgs" at "", but the current directory is "/Users/christianjara/ros/ros_comm/messages/std_msgs". You should double-check your ROS_PACKAGE_PATH to ensure that packages are found in the correct precedence order. Call Stack (most recent call first): /Users/christianjara/ros/ros/core/rosbuild/public.cmake:180 (_rosbuild_check_package_location) CMakeLists.txt:7 (rosbuild_init)

-- Configuring incomplete, errors occurred!*

Any tips on how to troubleshoot this would be gratefully appreciated.

Thanks!
