platform darwin 10 {
    if {${configure.cxx_stdlib} eq "libc++"} {
        ...
   }
}

or (if you additionally to include a few more OS versions):

platform darwin {
    if {${os.major} == 10} {
        if {${configure.cxx_stdlib} eq "libc++"} {
            ...
        }
   }
}

It depends on what exactly you need. Note that libc++ is also not
default on 10.8 and that it can be (painfully) made to work on 10.5.

Maybe you can exaplain a bit more about what you want to achieve.
