That's not a compilation error but rather a run-time error.

My guess would be that you have multiple versions of FreeType and the wrong one is picked up. It seems as if you have an odd mix of homebrew and X11 which may be the problem. Did you compile everything from source (including R)? If not, you'll have a hard time cleaning things up to work with the system libraries, R and homebrew -- I'd recommend staying away from trying to mix all three together (i.e., use either CRAN or homebrew but not both).

Cheers,
