C++ 2.0 library fails to compile on OSX 10.9.5.

[Nathan Gleaves]

I am getting a compilation error when building the driver from source. This could be due to me not being very familiar with c++ but... Maybe someone here will have some idea of how to help.


pulled gitbug repo.
made build cirectory
cd to build directory
cmake ..
make

Hey, sorry about that. That was last minute compile fix for Ubuntu 14.04/12.04, but it wasn't compatible with Mac. Push a fix: https://github.com/datastax/cpp-driver/commit/c355999edbd5cbc2395863d4f250a9c0ee409d48

Thanks for reporting!
