Dear All,
I try to install ros on my linux system (Arch Linux 32bit), I use this 
guide http://www.ros.org/wiki/diamondback/Installation/Arch to install 
it. but when I digit

rosinstall ~/ros 

I receive this message:

Traceback (most recent call last):
   File "/usr/bin/rosinstall", line 5, in <module>
     pkg_resources.run_script('rosinstall==0.5.16', 'rosinstall')
   File "/usr/lib/python2.7/site-packages/pkg_resources.py", line 499, 
in run_script
     self.require(requires)[0].run_script(script_name, ns)
   File "/usr/lib/python2.7/site-packages/pkg_resources.py", line 1235, 
in run_script
     execfile(script_filename, namespace, namespace)
line 23, in <module>
     import yaml
ImportError: No module named yaml

Since that when I had to use sudo easy_install-2.7 instead sudo 
easy_install because "easy_install" doesn't work in my distribution.
