No, but now that I tried it, this particular problem went away. Now I
can replicate the following:

Compiling libnetutil
cd libnetutil && gmake
gmake[1]: Entering directory '/home/root/nmap-6.46/libnetutil'
g++ -c -I../liblinear -I../liblua -I../libdnet-stripped/include
-I../libpcre  -I../libpcap -I../nbase -I../nsock/include -DHAVE_CONFIG_H
-D_FORTIFY_SOURCE=2 -g -O2 -Wall -fno-strict-aliasing netutil.cc -o
netutil.o
netutil.cc: In function 'int send_ipv6_ip(const sockaddr_in6*, const
unsigned char*, size_t)':
netutil.cc:3841: error: aggregate 'iovec iov' has incomplete type and
cannot be defined
Makefile:37: recipe for target 'netutil.o' failed
gmake[1]: *** [netutil.o] Error 1
gmake[1]: Leaving directory '/home/root/nmap-6.46/libnetutil'
Makefile:143: recipe for target 'netutil_build' failed
gmake: *** [netutil_build] Error 2

After adding #include <sys/uio.h> to netutil.cc, it compiles fine.
