Comment (by nicos@…):

 In the end, I did not encounter this error when testing ports again on
 Mavericks.

 As a follow-up, I noticed that on more recent installs, the file
 /opt/local/include/Qt/qglobal.h is only a stub pointing to:
 {{{
 #include "../QtCore/qglobal.h"
 }}}

 Then, on my system, testing for the variable shows that it is present:
 {{{
 grep QT_VISIBILITY_AVAILABLE /opt/local/include/QtCore/qglobal.h
 #  define QT_VISIBILITY_AVAILABLE
 #  elif defined(QT_VISIBILITY_AVAILABLE)
 }}}
