sudo problems

[David A. Bandel]

Folks,

First, happy new year.

Now for the puzzle.  Today I ran into this:
sudo: /etc/sudoers is owned by gid 40, should be 0
sudo: no valid sudoers sources found, quitting
sudo: unable to initialize policy plugin

_very_ odd as you can see here:

david at sanpablo:/usr/src/chromiumos$ ls -al /etc/sudoers*
-r--r----- 1 root root  507 Jan 23  2012 /etc/sudoers

/etc/sudoers.d:
total 32
drwxr-xr-x   2 root root  4096 Jan  1 18:01 .
drwxr-xr-x 224 root root 16384 Jan  1 09:50 ..
-r--r-----   1 root root   958 Nov 12  2011 README
-r--r-----   1 root root   361 May 30  2012 hobbit
-r--r-----   1 root root    53 Jan  1 18:01 relax_requirements

Nothing makes sense here.  gid 40 is src (one of my secondary gids,
but not my primary).  The subdirectory I'm in using sudo is group src.
 Other than that, I have no idea where this might be coming from.
Google has told me nothing that pertains (folks with this problem all
had their permissions hosed, whereas mine are correct).

Ideas?

TIA,

David A. Bandel
