"Not supported" error message is very misleading

[ToyboxZach]

This package throws a "not supported" error message in most cases that this package is just not set up correctly.

I just wasted a good deal of time trying to figure out what was going on. I would suggest maybe adding in details about making sure the package is setup correctly (pod install, xcode config etc) could save a lot of time for a lot of developers.
