Four different boxes of ours:

$ uname -r && ls -ld /usr/ports
6.2-STABLE
drwxr-xr-x   69 root      wheel     2048 10 Nov 02:14 /usr/ports/

$ uname -r && ls -ld /usr/ports
6.3-PRERELEASE
drwxr-xr-x   69 root      wheel     1536 10 Nov 02:12 /usr/ports/

$ uname -r && ls -ld /usr/ports
7.0-PRERELEASE
drwxr-xr-x   69 root      wheel     1536  7 Nov 02:24 /usr/ports/

$ uname -r && ls -ld /usr/ports
7.0-BETA2
drwxr-xr-x   69 root      wheel     1536 10 Nov 02:19 /usr/ports/

Sounds like you may have a security problem (re: "31337" GID).  If
that's the case, I would strongly advocate formatting + reinstalling
those machines.
