Yes, 5.7.1 .

During the build lrelease is invoked through a wrapper which sets

LD_LIBRARY_PATH=/path/to/build/qtbase/lib${LD_LIBRARY_PATH:+:$LD_LIBRARY_PATH}

that looks correct to me.

That must be it:

For lrelease:
  RPATH                $ORIGIN/../lib:/opt/local/lib:/opt/local/libexec/qt5/lib

For qtdiag:
  RUNPATH              $ORIGIN/../lib:/opt/local/lib:/opt/local/libexec/qt5/lib
