support for wireless card not built into kismet

[Ray Phillips <r.phillips%uq.edu.au@localhost>]

I've tried to run kismet compiled from pkgsrc under NetBSD/i386 5.1 
on a Toshiba Tecra A7 which has an Intel wireless card.  This is part 
of dmesg's ouput:

wpi0 at pci4 dev 0 function 0: vendor 0x8086 product 0x4222 (rev. 0x02)
wpi0: interrupting at ioapic0 pin 18
wpi0: MoW1, address 00:13:02:17:22:d0
wpi0: 11a rates: 6Mbps 9Mbps 12Mbps 18Mbps 24Mbps 36Mbps 48Mbps 54Mbps
wpi0: 11b rates: 1Mbps 2Mbps 5.5Mbps 11Mbps
wpi0: 11g rates: 1Mbps 2Mbps 5.5Mbps 11Mbps 6Mbps 9Mbps 12Mbps 18Mbps 
24Mbps 36M

Since the man page for wpi(4) says it's the driver for the Intel 
PRO/Wireless 3945AB, I added this line to 
/usr/pkg/etc/kismet/kismet.conf:

source=ipw3945,wpi0,addme

but when it's run kismet says:

FATAL: Support for capture source type 'ipw3945' was not built. 
Check the output from 'configure' for more information about why it 
might not have been compiled in.

What steps should I follow to get the kismet package to build with 
support for the 3945ABG?
