Hello,

I am trying to build ftpsesame from wip under  DragonFly 1.5.3-DEVELOPMENT and it drops the following errors:

Looks trivial that it cannot find the header 
file.It is /usr/include/net/pf/pfvar.h but if I edit the patch.a file (I am a non-programmer!) the checksum becomes invalid. Any ways to work this problem around? This package would be essential for me.
