Ruby pcap and windows

Hello all, I need to send SYN packets and check whether SYN ACK packets
are received. I was looking at rubyforger, which seems to allow me to
do this quite easily. However, rubyforger is dependent on ruby pcap and
ruby pcap doesnt seem to install on windows. Has anybody successfully
done so or has a suggestion how I could create the needed code without
rubyforger and pcap?
Thanks-
Christian
