Yes. If you install one port with the quartz variant, really you  
should install all ports with it, and vice versa. pango has specific  
checks for this, but even for those that don't, this holds true.

It's this:

In MacPorts, the quartz variant is often the way you indicate you want  
native Mac OS X drawing routines to be used instead of the default X11  
drawing routines. However, these are less-well tested and so might not  
work.
