So you either installed coreutils +with_default_names or made that 
symlink by hand. Which one is the case?

The man page for ls from coreutils is at 'man gls'. Maybe there is a bug 
in coreutils which still installs the man pages with the 'g' prefix even 
if +with_default_names is selected.

I would not recommend to overwrite the default ls from the system 
exactly for this reason. Scripts may rely on the default behavior.
