Sounds like a missing dependency. I'm not familiar with the ZBar code reader but I'd imagine it declares dependencies on some system frameworks that you haven't yet included in your app? Look in the docs for ZBar to determine which frameworks you need to link to when including it. Typically when you get these types of libtool errors when you don't include a framework or other dependency.
