adjust OSVERSION evaluation in ports that specifically use '100050N'.

Sponsored by: The FreeBSD Foundation
On FreeBSD 10.0, all configuration is installed under
/usr/local/etc/namedb and installs its own rc script in
$PREFIX, which no longer support chroot installations.
LINKS and REPLACE_BASE options are not supported on 10.0
for obvious reasons.
Note for FreeBSD 9.x and earlier users, LINKS is no longer
the default option, though still supported.
An UPDATING entry will follow after bind96 and bind99 are fixed
as well.
"--with-libiconv=${LOCALBASE}" at systems pre OSVERSION 100043 and "" (null)
otherwise;
. convert all ports which has CONFIGURE_ARGS=--with-libiconv=${LOCALBASE}.

9.6.x is not affected, neither is 10.x.
Security: CVE-2013-4854 Remote DOS
Security Fixes
Prevents exploitation of a runtime_check which can crash named
when satisfying a recursive query for particular malformed zones.
(CVE-2013-3919) [RT #33690]
A deliberately constructed combination of records could cause
named to hang while populating the additional section of a
response. (CVE-2012-5166) [RT #31090]
Now supports NAPTR regular expression validation on all platforms,
and avoids memory exhaustion compiling pathological regular
expressions. (CVE-2013-2266) [RT #32688]
Prevents named from aborting with a require assertion failure
on servers with DNS64 enabled. These crashes might occur as a
result of specific queries that are received. (CVE-2012-5688)
[RT #30792 / #30996]
Prevents an assertion failure in named when RPZ and DNS64 are
used together. (CVE-2012-5689) [RT #32141]

CVE-2012-5689
- address the issue raised by Bob Harold. RRL on recursive servers
applies rate limits after waiting for recursion except on
sub-domains of domains for which the server is authoritative.
- fix the bug reported by Roy Arends in which "slipped" NXDOMAIN
responses had rcode values of 0 (NoError) instead of 3 (NXDOMAIN).
- move reports of RRL drop and slip actions from the "queries"
log category to the "query-errors" category. Because they are not
in the "queres" category, enabling or disabling query logging no
longer affects them.
The change makes "slip 1;" send only truncated (TC=1) responses.
Without the change, "slip 1;" is the same as the default of "slip 2;".
That default, which alternates truncated with dropped responses
when the rate limit is exceeded, is better for authoritative DNS
servers, because it further reduces the amplification of an attack
from about 1X to about 0.5X.
DNS RRL is not recommended for recursive servers.
Feature safe: yes
Removed the check for regex.h in configure in order
to disable regex syntax checking, as it exposes
BIND to a critical flaw in libregex on some
platforms. [RT #32688]

A serious Multiple Zone Response Policy Zone (RPZ2)
Speed Improvement bug has been fixed.
`./configure --enable-rpz-nsip --enable-rpz-nsdname`
is now the default.
Responses affected by the all-per-second parameter
are always dropped. The slip value has no effect on them.
There are improved log messages for responses that aredropped or "slipped," because they would require an
excessive identical referral.
released version of January 5, 2013.
This also includes performance patches to the BIND9
Response Policy Zones (DNS RPZ), Single Zone Response
Policy Zone (RPZ) Speed Improvement, in the same
patch.

BIND 9 nameservers using the DNS64 IPv6 transition mechanism are
vulnerable to a software defect that allows a crafted query to
crash the server with a REQUIRE assertion failure. Remote
exploitation of this defect can be achieved without extensive
effort, resulting in a denial-of-service (DoS) vector against
affected servers.

CVE-2012-5688
Feature safe: yes
Prevents a crash when queried for a record whose RDATA exceeds
65535 bytes.
Prevents a crash when validating caused by using "Bad cache" data
before it has been initialized.
ISC_QUEUE handling for recursive clients was updated to address
a race condition that could cause a memory leak. This rarely
occurred with UDP clients, but could be a significant problem
for a server handling a steady rate of TCP queries.
A condition has been corrected where improper handling of
zero-length RDATA could cause undesirable behavior, including
termination of the named process.
