wrong _source notation: changed colon to slash notation

Sorry, copy fail. I want to fix following error after 'bower install fastdom':

bower fastdom#* ECMDERR Failed to execute "git ls-remote --tags --heads git://github.com:wilsonpage/fastdom.git", exit code of #128
fatal: unable to connect to github.com:
github.com: Servname not supported for ai_socktype

Can you reproduce this error?
