Cool, as I initially suspected, defining _DARWIN_USE_64_BIT_INODE
at the appropriate place fixes things. This has been in place
since coreutils 8.13. I verified 8.14 works on your system.

Notes:
  Newer coreutils also fixed up the alignment
  coreutils diverges from POSIX and defaults to 1024 byte blocks
  The system df displays /net and /home even without -a. bug?
  The system df displays the capacity as 100%. bug?

cheers,
Pádraig.
