To mount '-t nfts-3g /dev/sdc2 /mnt/ntfspart -o rw'
You can just make a symlink like this:
ln -s /usr/bin/ntfs-3g /sbin/mount.ntfs-3g
I have made and use this patch that does this under compiling. I'm not sure if this is the proper or right way to do it, but it works for me, and I can mount ntfs-3g within LuCI.
