[cfe-users] official download unusable on centos 6?

[kang joni via cfe-users]

I downloaded provided clang 3.8 for centos6 and got bunch of errors like these:

./clang: /lib64/libc.so.6: version `GLIBC_2.15' not found (required by ./clang)
./clang: /lib64/libc.so.6: version `GLIBC_2.14' not found (required by ./clang)
./clang: /usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.14' not found
(required by ./clang)
./clang: /usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.18' not found
(required by ./clang)
./clang: /usr/lib64/libstdc++.so.6: version `CXXABI_1.3.5' not found
(required by ./clang)
./clang: /usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.15' not found
(required by ./clang)

how to use clang c++11 on centos6 the easy way?
I saw clang 3.4.2 on epel release but I'm unsure how to build libcxx
to use c++11 since there was no libcxxabi at that time? Any good
tutorial?
thanks.
