install.packages('stringi') fails on OSX Yosemite, R 3.2.1

[jucor]

Hi folks

On my OSX Yosemite with R 3.2.1, install.packages('stringi') fails due to /lib/cpp failing sanity check. Using the pre-compiled Mavericks binary install.packages('stringi', type='mac.binary.mavericks') works, but that's not ideal.

Thanks for any help!

My setup

I have Xcode installed, with clang, and set the variables correctly:

$ cat ~/.R/Makevars 
CC=clang
CXX=clang++

My SessionInfo():

> sessionInfo()
R version 3.2.1 (2015-06-18)
Platform: x86_64-apple-darwin10.8.0 (64-bit)
Running under: OS X 10.10.3 (Yosemite)

locale:
[1] en_GB.UTF-8/en_GB.UTF-8/en_GB.UTF-8/C/en_GB.UTF-8/en_GB.UTF-8

attached base packages:
[1] stats     graphics  grDevices utils     datasets  methods   base     

loaded via a namespace (and not attached):
[1] tools_3.2.1
> 

Possible cause?

However, it seems that stringi's configure line 3221 is still falling back on /lib/cpp.

I have no idea how to fix that, sorry.

Other setup I tried

I pointed CC and CXX variables to a homebrew-installed gcc49, but same problem.

You have a misconfigured C++11 compiler settings set. Upgrade it or try the latest git version of stringi.
