Nmap 6.47 [2014-08-20]

o Integrated all of your IPv4 OS fingerprint submissions since June 2013
  (2700+ of them). Added 366 fingerprints, bringing the new total to 4485.
  Additions include Linux 3.10 - 3.14, iOS 7, OpenBSD 5.4 - 5.5, FreeBSD 9.2,
  OS X 10.9, Android 4.3, and more. Many existing fingerprints were improved.
  Highlights: http://seclists.org/nmap-dev/2014/q3/325 [Daniel Miller]

o Removed the External Entity Declaration from the DOCTYPE in Nmap's XML. This
  was added in 6.45, and resulted in trouble for Nmap XML parsers without
  network access, as well as increased traffic to Nmap's servers. The doctype
  is now:
  <!DOCTYPE nmaprun>

o [Ncat] Fixed SOCKS5 username/password authentication. The password length was
  being written in the wrong place, so authentication could not succeed.
  Reported with patch by Pierluigi Vittori.

o Avoid formatting NULL as "%s" when running nmap --iflist. GNU libc converts
  this to the string "(null)", but it caused segfault on Solaris. [Daniel Miller]

o Handle ICMP admin-prohibited messages when doing service version detection.
  Crash reported by Nathan Stocks was: Unexpected error in NSE_TYPE_READ
  callback.  Error code: 101 (Network is unreachable) [David Fifield]

o [NSE] Fix a bug causing http.head to not honor redirects. [Patrik Karlsson]

www/squid33: Support Kerberos on DragonFly

DragonFly does not have Kerberos in the base system as this port assumes.
In order to build squid33, DF has a dependency on krb5 packages.  Morever,
the configure check assumes Kerberos is in the base system, so it fails
to configure.  Disable the check completely as it's guaranteed to pass on
FreeBSD and the sought headers are installed with krb5.
security/xzid: suppress broken and unnecesary missing target check

Line 606 of the vendor Makefile has a malformed error message that comes
up if the makefile is given no target.  For reasons I don't understand,
the gmake on FreeBSD tolerates it and the same exact gmake on DragonFly
catches it.  Just amend the sed command the remove the line completely
as it's never executed in the ports framework.
