I'm using Cocoapods 0.16.3
For pod spec issues you should file tickets on the spec repo.
Having said that, the spec probably has to be fixed because of the first item in the 0.16.3 changelog bug fixes list. I’m guessing that framework_path should be something like GoogleMaps-iOS-1.1.0/GoogleMaps.framework.
Please CC the spec author (@ryanmaxwell) when you create the pull-request/ticket.
Yup it seems to be an issue with the spec and cocoapods 0.16.3. I'll look into it tomorrow but if anyone has a chance to fix in the meantime it would be much appreciated
