I try to do run rosinstall on my mac book pro:

delirium-tremens:~ serge$ rosinstall ~/ros/ "
http://packages.ros.org/cgi-bin/gen_rosinstall.py?rosdistro=diamondback&variant=desktop-full&overlay=no
"

Traceback (most recent call last):
  File "/usr/local/bin/rosinstall", line 5, in <module>
    pkg_resources.run_script('rosinstall==0.5.16', 'rosinstall')
  File
"/System/Library/Frameworks/Python.framework/Versions/2.6/Extras/lib/python/pkg_resources.py",
line 442, in run_script
    self.require(requires)[0].run_script(script_name, ns)
  File
"/System/Library/Frameworks/Python.framework/Versions/2.6/Extras/lib/python/pkg_resources.py",
line 1167, in run_script
    exec script_code in namespace, namespace
  File
"/Library/Python/2.6/site-packages/rosinstall-0.5.16-py2.6.egg/EGG-INFO/scripts/rosinstall",
line 23, in <module>

ImportError: No module named yaml

=========================================

I guess because rosintall do not use the right Python path.
How did you install rosinstall ?

Regards,
