This sounds like you did NOT mount the usr partition properly on /usr.

This sounds like sd0g is NOT what you thing it is. Either it is no BSD
partition at all, or it is the usr partition all right, but was never newfs'd
(maybe due to the same error as above).

Sometimes people miss the part of the installation dialog, where you add
additional (to root) file systems. The dialog goes like this:

        ===
You will now have the opportunity to enter filesystem information.
You will be prompted for device name and mount point (full path,
including the prepending '/' character).

Note that these do not have to be in any particular order.  You will
be given the opportunity to edit the resulting 'fstab' file before
any of the filesystems are mounted.  At that time you will be able
to resolve any filesystem order dependencies.

The following will be used for the root filesystem:
        /dev/sd0a       /

Device name? [done]

        ===

and at that prompt, you should have entered "/dev/sd0g" (if that is the
usr partition) and then, when it asks "Mount point? ", you answer "/usr".
Did you do this?
