[R-SIG-Mac] Problem with Rcpp on R-3.4 beta (r72492)

I have downloaded and installed R from R-3.4-r72492-branch-el-capitan.pkg.
My OS: OS X El Capitan (10.11.6)

My packages and all additional tests of these are working correctly.

I can install Rcpp.
Packages requiring Rcpp however don't seem to install or run.

Running otool -L on /Library/Frameworks/R.framework/Versions/3.4/Resources/library/Rcpp/libs/Rcpp.so

	Rcpp.so (compatibility version 0.0.0, current version 0.0.0)
	/Library/Frameworks/R.framework/Versions/3.4/Resources/lib/libR.dylib (compatibility version 3.4.0, current version 3.4.0)
	/System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation (compatibility version 150.0.0, current version 1259.0.0)
	/usr/local/clang4/lib/libc++.1.dylib (compatibility version 1.0.0, current version 1.0.0)
	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1226.10.1)

I don't have  /usr/local/clang4/lib/libc++.1.dylib.
I wouldn't know where to get it from. AFAIK The macOS Commandline Tools do not install stuff in /usr/local.
If this isn't a mishap: where do we get the necessary libc++.1.dylib from?
