FWIW I get these errors (and some others related to conflicting
uint64_t definitions) on this:
CentOS release 5.6 (Final)

What is your kernel version?
I guess you're running an old kernel without recvmmsg(). So the kernel
headers are missing the mmsghdr struct.
If you would like to contribute a patch to fix this, please introduce a
CONFIG_L2TPV3 variable in ./configure and check for mmsghdr with a small
C test that declares a variable using this struct.
Then modify net/Makefile.objs to switch l2tpv3.o from CONFIG_LINUX to
your new CONFIG_L2TPV3 variable. This way it only gets built on hosts
that support mmsghdr.
You can find examples of other compile tests in ./configure.
If not, let us know and either I or Anton will fix this problem.
