Please check with r-sig-mac and other macOS experts. On systems that are set-up correctly, the package installs and checks correctly as you can see at the CRAN status page. This includes the macOS platforms. I don't work on, or with, macOS so I really cannot help. Truly sorry. The package as such is fine.

[eddelbuettel]

You could also post and ask on the (generally friendly and low-volume) rcpp-devel list (subscribe first to post) where other macOS users should be able to help you with the setup.
