Barr is anti-tax and pro-gun, both of which are platforms embraced by both the Lib and repub parties. But that's about where the similarities end. He wrote the "Defense of Marriage Act," led the Clinton impeachment effort and (until he started running for the Libertarian nod) was steadfast in his support for the failed "War on Drugs," to the point of opposing medical Marijuana. He even tried to ban the practice of Wicca in the Military. Not much of a (small-l) "libertarian."
