Trying to compile tcpxtract on mac osx gives i386 symbol not found

Trying to compile tcpxtract on mac osx gives i386 symbol not found

I am doing some testing today and was searching for a command line program
that would allow me to extract files out of tcp traffic, I seem to have
found one called tcpxtract, however when I try to compile it, I get the
following error on make
Undefined symbols for architecture i386:
"_yywrap", referenced from:
_yylex in confl.o
_input in confl.o
ld: symbol(s) not found for architecture i386
collect2: ld returned 1 exit status
make: *** [tcpxtract] Error 1
What can I do to get it to compile?
I'm on a Macbook Pro Retina Early 2013 running 0SX 10.8.4
