How do I install rpy2 when clang doesn't support OpenMP (Mac OSX)?

I am trying to use pip to install rpy2 on OSX 10.12.5. I get this error:

clang: error: unsupported option '-fopenmp'
clang: error: unsupported option '-fopenmp'
error: command '/usr/bin/clang' failed with exit status 1

From what I understand, this is because my version of clang does not support OpenMP. Using homebrew, I installed LLVM 8.1.0 (clang 802.0.42), but now I need to update clang to support OpenMP. Can anyone give me detailed instructions of how to go about this? I am not understanding the other sources I am reading online.

I just got rpy2-2.9.0 to install via pip on Mac OSX 10.13, after getting the same error you reported, by downgrading to R 3.3.3, downloaded from https://cran.r-project.org/bin/macosx/. I just re-installed R 3.3.3 then re-ran 'pip install rpy2' and it installed fine.
