yes i believe the author of that went through some troubles a while back

mind if i ask which distro you were able to successfully luksFormat to
in cryptsetup 1.6.2 issuing:

cryptsetup --debug --hash sha512 --cipher twofish-xts-plain64
--use-random --key-size 256 --iter-time 2000 luksFormat /dev/md0

what were your compile switches ?
