The clang-4.0 dependency on a stock unmodified 10.8.5 system comes from the
cxx11 1.1 portgroup being include in qt5, which whitelists this compiler for
you.
if {${cxx_stdlib} eq "libstdc++" } {
compiler.blacklist-append {macports-clang-3.[0-8]} clang
compiler.whitelist-append \
macports-clang-4.0 \
The full file is here:
/opt/macports-ports/_resources/port1.0/group/cxx11-1.1.tcl
For your other situation where the cxx_stdlib has been set to libc++, this
whitelisting will not be forced, and you’ll go back to default to clang-3.9,
which has been set in your macports.conf default_compilers setting.
Best,
