Problem using packages: or NOT operator?

[Villalovos, John L]

I started trying to use the packages command.  So I did the following:

Does NOT work.  Using the Logical NOT operator and define=:
-----------------------------
packages:
    redhat::
        vim-enhanced define=hasVimEnhanced

shellcommands:
    # Install vim-enhanced if it is not already installed.
     !hasVimEnhanced::
            "/usr/sbin/up2date vim-enhanced"



But this did work using elsedefine= and not using the logical NOT
operator:
-----------------------------------
packages:
    redhat::
        vim-enhanced elsedefine=needVimEnhanced

shellcommands:
    # Install vim-enhanced if it is not already installed.
     needVimEnhanced::
            "/usr/sbin/up2date vim-enhanced"



Any ideas on this behavior?

Thanks,
John
