LinuxQuestions.org - Weplab not installing

I'm attempting to install weplab, but for some reason I am getting an error whenever I try to run "make".

The error reads as follows:

Code:

gcc  -DG_DISABLE_ASSERT -O3  -fomit-frame-pointer -fno-exceptions -pipe -s -ffast-math -fexpensive-optimizations -falign-functions -falign-loops -fstrict-aliasing  -o weplab  main.o analpfile.o bruteforce.o capture.o debug.o dictionary.o globals.o heuristics.o md5.o wep.o attack.o  -lpcap

capture.o(.text+0x31e): In function `captureWeakPackets':

: undefined reference to `pcap_dump_flush'

collect2: ld returned 1 exit status

make: *** [weplab] Error 1

All I have done up to this point was untar the directory, and run ./configure. Thanks for any help.
