Error Information: ERROR: compilation

I have very little programming knowledge, so I hope you will excuse me if the question is trivial. I am using a mac and I am trying to install an R package from Github.


Unfortunately the installation fails due to some compilation problem.

Here is the error message I ger:

Does anyone know what is going wrong? and could anyone tell me how to fix this?
