I attempted to install Fuerte on OS X using MacPorts instead of HomeBrew.  
- I first installed all dependencies through MacPorts except wxPython and Ogre (FYI, I just added a py27-empy port in MacPorts).
- I made it easier for ROS to do the right thing by doing this:
	sudo port select python python27
	sudo port select nosetests nosetests27
- I installed wxPython2.9-osx-2.9.2.4-cocoa-py2.7 via binary installer (the 2.9.3 release resulted in linking errors apparently this is a known issue: http://forums.wxwidgets.org/viewtopic.php?f=19&t=34185)
- I added /opt/local/Library/Frameworks/Python.framework/Versions/2.7/bin to PATH
- Installed the core libraries like so (cmake needs to find wx-config):
	env PATH=/usr/local/lib/wxPython/bin:${PATH} cmake .. -DCMAKE_INSTALL_PREFIX=/opt/local/fuerte

- Eventually, I got stuck in section 1.7, "Build Higher-level/tools (Layer 2)”, with this error:

> rosdep install -a
