I don't know if any methods, exist, but you could hack it up if you
have the 'ip' package installed on your system, ie. 'ip show route'
doesn't say the command wasn't found.
Then you can try:

# get your gateway IP address
gateway = `ip route
show`.match(/default.*/)[0].match(/\d\d?\d?\.\d\d?\d?\.\d\d?\d?\.\d\d?\d?/)[0]
# get the mac address for the gateway
mac_address = `ip neigh
show`.match(/#{gateway}.*/)[0].match(/..:..:..:..:..:../)[0]
