Both /usr and /var are full. ffs filesystems need to have a certain amount
of free space to operate correctly, so the "100%" capacity size is less
than the size of the drive in blocks.
As root, you can fill the disk above the "100%" capacity. Other users,
though, can't.
Try deleting some stuff and you should be fine. I find the unformatted man
pages are a good candidate (depending on the version, they might be
installed).
Take care,
