The link I provided to the httpuv issue has detailed information about
the error:

The error occurs when I run the following (although note, depending on
which mirror you use, the recent CRAN server issues may result in
problems downloading the packages):
  install.packages("httpuv", type = "source")

Here's the full output:

Here's an example of the errors:

note: 'uid_t' declared here

This issue describes the same problem:

And it has been fixed in the development version of Rcpp by:

I know that Kevin Ushey has tried building with the CRAN-recommended
clang 7 toolchain and encountered the same errors. I haven't done that
yet myself, though.

> That said, I have run httpuv by hand on the CRAN build machine (against Rcpp 1.0.4) and I saw no issues. I have seen the discussion on Rcpp, but so far no one actually posted details of what is breaking (nor do your links include any actual details on this). I'd love to help, but the lack fo a useful report makes this impossible. If you have any actual leads, please post them. The CRAN machine uses the tools that are available on CRAN: https://cran.r-project.org/bin/macosx/tools/ (clang-7 and gfortran-6.1 for 3.6.x)
