Replace all the $MKFS_PROG.$FSTYP invocations with $MKFS_PROG -t $FSTYP. The mkfs wrapper binary knows how to search the user's $PATH to find the appropriate mkfs delegate, which the author uses to switch between development and distro versions of various tools. Unfortunately, using "$MKFS_PROG.$FSTYP" means that the shell only looks in the same directory as the mkfs wrapper, which means that we can end up mixing different tool versions when this is the case.
