Does anyone know what packages I need in order to build the orocos
toolchain on unbuntu 12.04?

I got the sources from:
awagner@dash:/home/awagner/src/orocos/orocos_toolchain
$ git remote -v
origin http://git.gitorious.org/orocos-toolchain/orocos_toolchain.git (fetch)

I have installed:

$ aptitude search catkin | grep "^i"
i python-catkin-pkg - catkin package library
i ros-groovy-catkin - Low-level build system macros and infrastr
i ros-hydro-catkin - Low-level build system macros and infrastr

These packages did not provide any catkin_make or catkin_make_isolated
programs that I've seen referenced in some comments:

$ catkin_ <tab> <tab>
catkin_create_pkg
catkin_find_pkg
catkin_generate_changelog
catkin_tag_changelog
catkin_test_changelog

Thanks! -Andrew
