Cannot install IDSwakeup due to LibNet

So I did download IDSwakeup and installed libnet and hping3 from ubuntu repositories. When I try to "make" IDSwakeup I get the following error:

gcc  -o iwu iwu.o -lnet ; \

iwu.o: In function `main':
iwu.c:(.text.startup+0x148): undefined reference to `libnet_open_raw_sock'
iwu.c:(.text.startup+0x26b): undefined reference to `libnet_write_ip'
collect2: error: ld returned 1 exit status
make: *** [iwu] Error 1

What I am doing wrong? I tried to reinstall libnet several times.
