Comment (by rjvbertin@…):

 somehow uses the 10.10 SDK).

 Preliminary results indicate that this is indeed the case and that at
 least on OS X 10.9, Qt5 should be built with `-sdk macosx10.9` :

 {{{
    if {${configure.sdkroot} ne ""} {
        configure.args-append \
            -sdk [string tolower [join [lrange [split [lindex [split
 ${configure.sdkroot} "/"] end] "."] 0 end-1] "."]]
 -    }
 +    } else {
 +        # default: build for the current OS version, requesting the
 corresponding SDK explicitly
 +        configure.args-append \
 +            -sdk [string tolower "macosx10.[expr ${os.major} - 4]"]
 +    }
 }}}

 unless someone can come up with a good argument why it's preferable always
 to build with the latest SDK available, even if it's newer than the host
 OS?
