eh ... what?!
What kind of a maniac came up with the idea that binutils should be replaced by python scripts?
What distro is that?
What's the output of
/usr/bin/which ls
If its anything other than "/bin/ls", then you $PATH environment variable is messed up. You can print that one with
echo $PATH
You might also want to check if the ls command is aliased:
alias ls
It should be:
alias ls='ls --color=auto'
