Hello, folks!

I'm using pkg-config from C++ 11 driver and got this errors from cmake and pkg-config tool:
Requires.private field occurs twice in '/opt/fastnetmon/libraries/mongo_cxx_3_0_0_rc0/lib/pkgconfig/libmongocxx.pc'
Requires.private field occurs twice in '/opt/fastnetmon/libraries/mongo_cxx_3_0_0_rc0/lib/pkgconfig/libmongocxx.pc'
Requires.private field occurs twice in '/opt/fastnetmon/libraries/mongo_cxx_3_0_0_rc0/lib/pkgconfig/libmongocxx.pc'

Requires.private field occurs twice in '/opt/fastnetmon/libraries/mongo_cxx_3_0_0_rc0/lib/pkgconfig/libmongocxx.pc'

So you definitely has an issue here:
cat /opt/fastnetmon/libraries/mongo_cxx_3_0_0_rc0/lib/pkgconfig/libmongocxx.pc
Requires.private: libbson-1.0
Requires.private: libmongoc-1.0

But pkg-config documentation (http://people.freedesktop.org/~dbn/pkg-config-guide.html) speaking about another approach for multiple required modules:
Requires.private: libbson-1.0, libmongoc-1.0

Could you fix this?
