Libertarians need to clarify their stance on gay marriage to be more consistent with their other stances. It is not that Libertarians should be for government sanctioning of gay marriage, but that government should have no say so in who marries whom. It is a private contract between two individuals and should be seen as such. Of course, if you go back to the militant gay marriage proponents with that they will not support it, because to them it is not really about being free to marry whomever you would like, but to be able to derive government benefits from your relationship. Not a Libertarian ideal at all.

I support the idea of homosexual people (or any other people for that matter) being free to marry whomever they want. Why should I care as long as their choices do not affect me? But that is the whole point, it should NOT AFFECT ME. Marriage should not be an avenue to gaining more government benefits, or else it becomes something that the taxpayers should have a voice in. If you truly want the freedom to marry whomever you want, then fight to get the government out if the whole thing. Otherwise you appear to simply be looking for another way to suck on the government teat.
