uninstall install error after 'brew edit FORMULA'

[Xijie Jiao]

 The system is mac os 10.13.1. Since it is beyond 10.9, I followed the libstdc++ installation instruction. 

The first problem I met is that uninstall cannot be done since the packages have dependencies on each other. I solve this by using uninstall --ignore-dependencies. But in the first trial of install --build-from-source, I met a problem as follows. 

Do anyone know what causes this problem. And it asks me to choose an action, what should I do further?  Thanks!

It seems that it is a cmake error. In addition, I cannot use cmake command. Does this mean that I do not have cmake installed?
