strace:

open("/etc/sudoers", O_RDONLY)          = -1 EACCES
(Permission denied)
geteuid32()                             = 1
setresuid32(0, 0, 0)                    = 0
write(2, "sudo: ", 6sudo: )                   = 6
write(2, "can\'t open /etc/sudoers", 23can't open
/etc/sudoers) = 23
write(2, ": ", 2: )                       = 2
write(2, "Permission denied\n", 18Permission denied

picky@localhost /usr/bin $ ls -li sudo
314108 ---s--x--x 2 root root 106160 Apr 11 09:26 sudo
picky@localhost /usr/bin $ find . -inum 314108
./sudo
./sudoedit
picky@localhost /usr/bin $ ls -li sudoedit
314108 ---s--x--x 2 root root 106160 Apr 11 09:26
sudoedit
picky@localhost /usr/bin $

Just noticed this:

picky@localhost ~ $ ls /
ls: cannot open directory /: Permission denied
picky@localhost ~ $

picky can't even mount a floppy or write to it!

But picky's fstab is identical to heathen's. 

Only thing I can think of: recently had to do emerge
--metadata on account of CacheCorruption error.
