Clang does not understand gcc 5's new ABI. On linux systems that default to the new ABI (such as ubuntu 15.10), building with clang requires using C++ libraries built with the the old gcc ABI. When building with the clang protobuf lib, a common error is to load the gcc protobuf library at run time. When set, PROTOBUF_ROOT is added to rpath to make sure the correct lib is loaded. Adds a script to install clang and download and build boost and protobuf with boost.
