Adding GoogleOpenSource Framework cause duplicate files with some pods in GTMHTTPFetcher file

I need to add in my app the GooglePlus framework, so, I need to drag GooglePlus.framework and GoogleOpenSource.framework in my project. The problem is that I am using some Pods and they already use the file GTMHTTPFetcher. I have duplicates and I can compile my project.

What should I do to add GoogleOpenSource.framework without having this problem? I tried to add the other files to the project, but they don't implement ARC and I think that change all the files one by one is not a good solution. Any idea??

Thank you
