 that I do not know how to proceed with either of them ...

 To use the existing ports in the macports tree with qt4, uninstall mayavi
 and dependencies back to traitsgui and traitsbackendwx.  Then install
 traitsgui with the qt4 variant, e.g. "sudo port install py26-traitsgui
 +qt4".  You should see qt4 and py**-pyqt4 installed as dependencies,
 unless you already have them.  Then reinstall py**-mayavi.
