Expected Behavior:

The package should compile and install.

Actual Behavior:

It appears that libstdc++ is removed from XCode 10 in favor of libc++ (which has been deprecated by Apple for a while now on macOS systems). Therefore, this library will not compile via a pip install.

    clang: warning: libstdc++ is deprecated; move to libc++ with a minimum deployment target of OS X 10.9 [-Wdeprecated]
    ld: library not found for -lstdc++
    clang: error: linker command failed with exit code 1 (use -v to see invocation)
    error: command 'gcc' failed with exit status 1

This behavior is observed on a fresh macOS system and fresh XCode 10 install on macOS Mojave 10.14.
