Comment (by michaelld):

 I'll look into this. I -think- that ${prefix} here might be
 MACPORTS_PREFIX/libexec/qt4, not just MACPORTS_PREFIX as is typical. Back
 when we moved qt4-mac to be in libexec/qt4, we really tried to make the
 variables as flexible as possible but by default all dependent on one
 master that defines the top level directory.
