Jano,

Thanks for the hint, got it working!

This is the change that I made to make things work the way I needed.

## Ruby / eRuby ##

# menu.rhtml
# Menu item name is non-link if page name is the same as menu item name,
if not then menu item name is link.

<%

fname = File.basename ENV['SCRIPT_FILENAME']

if fname == 'index.rhtml'
puts 'Home &nbsp;&nbsp;::&nbsp;&nbsp;'

else
puts '<a href="index.rhtml" title="Home">Home</a> 
&nbsp;&nbsp;::&nbsp;&nbsp;'
end

%>
