I'm having an utterly bizarre issue while porting ocsigen.  If I run the
whole port build under sudo, it does something which results in:

shock avsm$ sudo ls
Illegal instruction
shock avsm$ md5 /usr/bin/sudo
md5: /usr/bin/sudo: Permission denied
shock avsm$ ls -la /usr/bin/sudo
-r-s--x--x  1 root  wheel  211232 24 Sep  2007 /usr/bin/sudo
shock avsm$ ls -la /dev/null
ls: /dev/null: No such file or directory

A reboot corrects the issue, and it happens every time.  If I run
the port destroot target without sudo, then it works fine and doesn't
appear to have any denied commands; so I was looking for a way to
explictly raise privileges and examine the command before it was
run as root.

Does this sort of problem ring any bells with anyone?
