[RndTbl] on-premise google analytics clone(ish)?

[Trevor Cordes]

For web traffic stats/graphing, back in the day we all ran webalizer, and
it's still ok.

Now many/most sites insert the little google analytics javascript code
link and get their stats there.  But google is evil, so....

Does anyone have any on-box (preferably FLOSS, but for-pay is an option
here too) web traffic stats/graphing tool they can personally recommend?
(Cloud need not apply.)

Does anyone know if any have js tie-in features like GA in order to get
the more juicy stats?  One would think it wouldn't be terribly difficult.

Thanks!
