Pcap library install on windows without c compiler


I need to find a gem or simple installer for the pcap library for
windows. I have found one but it is written in c and requires
make…make install… I don’t have access to a c compiler. Also I
am firewalled and proxied so I can only download via http/ftp no console
web access. Or could someone tell me which files to copy and where to
put them.
