[ros-users] rosdep and interdependent rosdeps

I am trying to get ROS going under OS X with homebrew, and I have run into
an issue.  Several packages depend on python-numpy, which I would like to
install through pip (homebrew doesn't provide a formula for this reason),
but before I do that I need homebrew to install gfortran.  So, do I add a
new rosdep to each package that also depends on numpy, or should there a
mechanism for inter package management dependencies.  I know you can have
several packages per installer rosdep (e.g. python: macports: python26
python_select), but that is only enough if both dependencies are in the same
package management system.

For now I have just added another rosdep (gfortran) that uses homebrew to
install and made that a dependency of roslib, but this is just a work

Something to think about,
