My single sentence may have been too concise, there are two concepts here: 1) the tool chain may or may not exist, and 2) bringing in that tool chain to the build system. Even if it's the "same" toolchain for compiling C++ as it is C, adding the complexity of an additional language to the build process, and the extra versioning headaches that C++ adds over C, is enough to kill library adoption. As I said originally, providing bindings is not the challenge, it's all the other stuff.
