qt4-mac infinite loop issue?

[Michael Dickens]

The issue was in how qt4-mac Portfile removed it's dependency on qt4-mac.  What I checked in was:
{{{
depends_lib-delete  bin:qmake:qt4-mac
}}}
because that was what was in the qt4 PortGroup.  In r72637, Ryan changed this notation in the PortGroup to read:
{{{
depends_lib-append  path:bin/qmake:qt4-mac
}}}
but not in the qt4-mac Portfile's deletion of it -- so the delete was not working.  So now in r72678, I just changed the notation in the Portfile to match that in the PortGroup, and hopefully that will take care of his issue (it does for me, when I do "port info qt4-mac" there is no dependency on qt4-mac).
