When you do su, put a dash after it so you won't have a problem finding programs.
su -

No bother at all!

The information from: man su says this...
Code:
    -, -l, --login
              make the shell a login shell

    A mere - implies -l.   If USER not given, assume root.
And googling around, I see this diddy.
"The - option establishes a default environment for the user."

So, if I just type: su fred, I am not really in the same place as if I typed su -l fred or even drop the l and just su - fred.

All you really need to know is that ( su - ) is what I always use so I don't have problems locating programs and commands as the root user.
