rsync fails to build on 10-stable sparc64

[cross+freebsd at distal.com]

  I have a sparc64 box running a stable-10 that’s a few months old, but 10.2_STABLE.  I’ve installed rsync from ports, rsync-3.1.0_2, and was just in the process of updating various ports.  I tried to build in /usr/ports/net/rsync, and it retrieved rsync 3.1.2, but trying to build the port rsync-3.1.2_1 produces the following failure.  I conducted the “portsnap fetch update” within the last hour.

  Is this a known problem?  Is it specific to sparc64?  Thanks.

                             - Chris
