Ntfs-3g help?

I am trying to get ntfs-3g to work, so I can mount ntfs partitions. I installed ntfs-3g from SFE - Software Packages for Solaris, OpenIndiana and OmniOS | Get your favourite software for (TM) Solaris 11, OpenIndiana Hipster, OmniOS as ready-to-use IPS packages Repository
There are VLC, Wine, etc.

I cannot get ntfs-3g to work. Anyone have a guess why? If I try as root, I get the same error message.

Meow:/mnt$ pfexec ntfs-3g /dev/dsk/c2t3d0p4 /mnt/Slask50GB_NTFS/

Please check '/devices/pci@0,0/pci15d9,818@1f,2/disk@3,0:u' and the ntfs-3g binary permissions,
and the mounting user ID. More explanation is provided at
