vim syntax highlight F9

[Marcelo M. Garcia]

Hi

How to enable syntax highlighting in vim? I tried to put "syntax on" on 
/etc/vimrc and on my "~/.vimrc" and does not work.  I have the following 
vim packages installed:
[root at newt set_new_machine]# yum list installed vim*
Loaded plugins: refresh-packagekit
Installed Packages
vim-common.i386                          2:7.1.291-1.fc9        
installed      
vim-enhanced.i386                        2:7.1.291-1.fc9        
installed      
vim-minimal.i386                         2:7.1.291-1.fc9        
installed      

Does anyone know how to solve this?

Thanks

Marcelo
