If I add --with-boost to my libMesh configure line, then it still uses the boost in contrib because it requires 1.61 or higher. If I update my external boost package to 1.61 then I guess it'd work fine, but I'd rather not do that right now... I'm not clear on why I'm getting a "previously defined" error, though... is it because by external boost library (from Ubuntu) is clashing with the boost in contrib?
