The current version of sysutils/bbcp (bbcp-20120520) does not
support data transfer over IPv6 (which is a problem in an
IPv6-only environment).  Please upgrade to a more recent
version, such as 14.07.01.00.0 (or at least 14.04.14.00.0).


The bbcp web page (http://www.slac.stanford.edu/~abh/bbcp/)
states the following changes:

  1.11  New Features

  Version 14.07.01.00.0 of documented here has the following new features:

  · The new –gross option forces bbcp to copy empty directory structures
    in recursive mode.

  · The new –mkdir option creates the destination directory for a
    recursive copy should it not exist.

  · The new –symlinks option specifies how symbolic links are to be
    handled during a recursive copy.

  Version 14.04.14.00.0 of documented here has the following new features:

  · Dual stack IPv6 mode is fully functional and is the default mode
    of operation. The new –ipv4 option forces bbcp to use the IPv4 TCP
    stack.

  · The new –license option prints the license under which bbcp is
    distributed.

  · The new –version option displays bbcp’s version number installed
    on the current host.

  · The BBCP_ALLOWPP environmental variable may be used to restrict
    program pipes to a specified set of programs or disable the feature
    altogether.


Note the license has changed with 14.04.14.00.0, previously it
was a BSD license, now it is a GNU Lesser General Public License.
