>Description:
I am running NetBSD 3.0 (from netbsd-3-0-RELEASE checked out on December 21), 
and using pkgsrc-2005Q4, up to date as of this PR. When attempting to build 
net/ORBit2, the build fails.

Note that this failure is related to my system being compiled and installed 
with the ``MKINET6=no'' in /etc/mk.conf, and as such I have no IPv6 support on 
my system.

Basically, AF_INET6 is defined when it shouldn't be. I'm not sure if this is 
simply because I haven't recompiled *all* of pkgsrc after recompiling base with 
``MKINET6=no'', however, that doesn't seem likely.

I can get this build to complete by modifying:

./work/ORBit2-2.12.2/linc2/src/linc-compat.h:

to include:

#undef AF_INET6

However, that should obviously be undefined to start with. I'm not familiar at 
all with autoconf and configure (or whatever other magic is used to set these 
things), so I can't help pinpoint the problem further.
>How-To-Repeat:
1. Build a system with ``MKINET6=no'' in ``/etc/mk.conf'':
2. Try to build net/ORBit2
>Fix:
Edit ``./work/ORBit2-2.12.2/linc2/src/linc-compat.h'' to include ``#undef 
AF_INET6''. This should demonstrate the build problem, but not the underlying 
issue with autoconf/configure.
