NTFS filesystem not recognized by mount

[Todd Wease]

Trying to mount ntfs partition gives an error that the filesystem is
unknown.

/dev/hda1  /mnt/winxp  ntfs  pamconsole,umask=000,ro 0 0

[wease1 at desktop: ~] $ sudo mount /mnt/winxp
mount: unknown filesystem type 'ntfs'
[wease1 at desktop: ~] $ sudo mount -t ntfs /dev/hda1 /mnt/winxp
mount: unknown filesystem type 'ntfs'

Is there something I'm doing wrong here or was support for ntfs not
compiled into the kernel or something else?  Thanks.
