Edit the makefile.  You'll see a section that looks like this:

ifeq ($(OSTYPE),macos)
CC = gcc -std=c99 -O2 -U__STRICT_ANSI__ -g -lm -lrt $(OS_CCDEFS) -I .
else
CC = gcc -std=c99 -O2 -U__STRICT_ANSI__ -g -lm $(OS_CCDEFS) -I .
endif

Remove everything except the second line.

NETWORK_OPT = -DUSE_NETWORK -isystem /usr/local/include
/usr/local/lib/libpcap.a

to:

NETWORK_OPT = -DUSE_NETWORK -lpcap
