issue with zsh is solved in the catkin reset_shell at https://github.com/ros/catkin/commits/reset_shell by http://answers.ros.org/users/2575/dirk-thomas/; so now I'm using zsh again.

I agree, thanks for encouraging to get things right with zsh. I filed an issue (#652) on https://github.com/ros/catkin/issues.

Problem solved!
My standard shell was zsh, I prefer this one over bash, and since it is supported in ros I decided to stick to zsh. With the problem with catkin_make I decided to switch to bash, because that might be better supported. However, I kept my standard shell to zsh.
Changing the shell with chsh -s /bin/bash (logging out and in again) and following the steps in the tutorial, did the job. So I can go on with ROS. Thanks for your help! Conclusion: I don't recommend zsh for ROS... (issue has been fixed, see below comment)

thank you for your suggestions! I've tried to do it in this order, again from scratch, but without result. Found somewhere the suggestion to add /usr to the CMAKE_PREFIX_PATH, but that doesn't help.

I work with a clean workspace, no packages. ROS Hydro was already installed in my virtual machine. After "sudo rosdep init" and "rosdep update", that seem to work properly, I generate my catkin workspace:

mkdir -p catkin_ws/src
cd ~/catkin_ws/src
catkin_init_workspace
source /opt/ros/hydro/setup.bash
cd ~/catkin_ws
catkin_make                       # do make on just clean catkin workspace

This gives the error as given above. Also after starting roscore the catkin_make gives the same error. The package catkin can be found:

$ rospack find catkin               # gives:
/opt/ros/hydro/share/catkin

However, the packages catkin_pkg or catkin-pkg cannot be found.

I'm following the building packages tutorial, but getting stuck at catkin_make on a brand new catkin workspace.

$ cd ~/catkin_ws $ catkin_make gives:

Apparently something goes wrong in generating the environment. Same problem happens when using the zshell instead of bash.

I'm using: ROS Hydro in an ubuntu virtual machine GNU bash, version 4.2.25(1)-release (i686-pc-linux-gnu) catkin 0.5.86 cat /proc/version: Linux version 3.2.0-60-generic-pae (buildd@allspice) (gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5) ) #91-Ubuntu SMP Wed Feb 19 04:14:56 UTC 2014

Any suggestions?

Further information, in reaction to comment 1:
