Hi, thanks for the report. Unfortunately I currently have no idea what may be causing it. You say libstdc++-devel is installed, and it provides the file in question. Your linked-to entry in the LLVM FAQ does not apply here as it mentions libraries, not applications. Looks like the file should be at /usr/include/c++/4.8.2/iostream - could you check whether that's the case? Because that directory is not listed in your output, so there may be something wrong with your compiler.

Thanks for your help, I have resolved this with some additional packages

sudo yum groupinstall "Development Tools"
sudo yum install libstdc++-static.x86_64 compat-libstdc++-33.x86_64
