sudo died when I ran kdemod

[Remix_eyeballs]

I was installing kdemod, and I was tweaking my xinitrc file to work.
I got an error message from kdemod that it couldn't find the command
'kdeinit'. I tried startx again, and after trying to start the server it
logged out. When I logged in sudo didn't recognize ANY command. i.e.

username@host ~$ sudo ls
sudo: ls: command not found

I reinstalled sudo with a new sudoers file and changed the 'root' to my username,
but it didn't work. Any idea what's wrong?

EDIT: 'halt' didn't work either.

EDIT2: Today I booted linux and I ran 'cd' which should take me to the home directory. I would think that that means that 'HOME' isn't set right. Isn't 'HOME' set by bash or '.bashrc'?

for getting root privileges your user has to be in "wheel" group. Make sure that your user is element of "wheel" group.
