>Description:
- Bump PORTREVISION.
- Remove FreeBSD 4.x code (USE_GCC=3.4+, USE_GETOPT_LONG and BROKEN).
- Use ARCH instead of MACHINE_ARCH for possible future cross-compilation support.
- Add UBLIO option, which uses devel/libublio for greatly improved speed (when reading an NTFS volume). Also print a warning when disabling UBLIO.
- Add pkg-message mentioning UBLIO.
- Change mount.ntfs-fuse -> mount_ntfs-fuse manpage link and symlink to the binary in /usr/sbin to allow using with 'mount -t ntfs-fuse' and in /etc/fstab after mounting /usr.
- Add a note in pkg-descr about the fusefs driver and ntfs-3g split project.
- Add LOCK option to avoid access to the device while it's mounted.

+ntfsprogs has been compiled with UBLIO support, to know more about it see
+"ports/sysutils/fusefs-ntfs/files/pkg-message.in".
+
+Note that there is no write support in this port, for that see the mentioned
+port. Also it's better for mounting the filesystem in general.
