:>Synopsis:       Problem using su
:>Description:
:I don't know if this is a bug or if its just me..but here it is:
:$ su
:su: you are not listed in the correct secondary group (wheel) to su root.
:$ id
:uid=1000(dustin) gid=0(wheel) groups=0(wheel)
:$

You've got a gid of 0 but you must also make sure you're also in /etc/group


su(1) says:
    Only users in group ``wheel'' (normally gid 0), as listed in /etc/group,
    can su to ``root'', unless group wheel does not exist or has no members.

/etc/group may well have, by default,
    wheel:*:0:root
