Compilation --with-netmap fails FreeBSD current

Hi,

Yesterday I reinstalled a system with the latest FreeBSD-Current and
tested that netmap works correctly with the pkt-gen application.

Today, I tried building click using sources that I pulled one day ago with
the following set of commands:

./configure --with-netmap

then I proceed to issue:

make

I got the following error:

In file included from ../include/click/packet.hh:4,
                 from ../include/click/element.hh:7,
                 from ../elements/userlevel/fromdevice.hh:3,

Stop in /root/click-latest.

Is this a known error? Is there another way I should be building click to
enable it to use netmap in a recent version of FreeBSD-Current?

Thanks,
