You might be able to use a test in a pre-fetch phase like (not tested at
all):

pre-fetch {
   if {![file exists ${prefix}/path/only/installed/by/variant]} {
      return -code error "Please install gtk2 with the +quartz"
   }
}

Though this is quite fragile, and really a bug in the dependency engine.
The real way around it is to get ticket #126 done:
