"wheel" is a standard group found on UNIX operating systems.

http://en.wikipedia.org/wiki/Wheel_(Unix_term)

On my system it's reversed:

$ ls -ld /opt{,/local}
drwxr-xr-x@  4 root  admin  136 Apr 25 03:28 /opt
drwxr-xr-x  20 root  wheel  680 Aug 13 05:57 /opt/local

However I would not think this difference would matter. I'm afraid I'm at a loss for why your system claims that files and directories that exist don't exist. There is something unusual about your computer, but I cannot figure out what it is.
