Xcode pod "library not found for"

After updating a pod and cleaning, we starting getting the following error:

library not found for -lAppirater

Apparently when updating pods, the Pod's project file gets completely changed.  Users on stackoverflow suggested setting your "Build Active Architecture Only" in the Pod's project settings to the same setting in your app's project setting.  After looking at that setting, we found that that setting did change in the Pod project.
