sudo fails to start with open(): No such file or directory

[IC Raibow]

Binary package hint: sudo

In a fresh install of 10.04 beta1 any sudo fails like this:

wiz@natali:~$ sudo
open(): No such file or directory
wiz@natali:~$

I had updated to latest repos and sudo's still broken.

Installed clean 10.04, did update/upgrade and here it is - broken ):

Found the source. I've made an alias for sudo in my .bashrc and it calls nonexistent binary first. My fault.
