I was attempting to modify the menus on the default Gnome desktop of SL 
6.  In RHEL 5, this feature was available by default through a GUI 
rather than editing files in the various menu configuration directories. 
  The application that supplies a GUI to do this is not loaded by 
default into RHEL 6.  Here is the relevant information:

The package in question is called
alacarte and may be installed either using the command line or the 
Add/Remove Software tool.

The actual invocation of alacarte is:


/usr/bin/python2.4 -OOt /usr/bin/alacarte

or whatever is the current version of python on the system
