-current with ports in endless loop

[Nilton Jose Rizzo]

   I'm tring to instal xfce4 with optimazed options
but it's run in endless loop.  How do I detect the ports 
start a loop?  If it's possible create a dot (.)
file in directory of port like .killloop like other
.extrac.done to prevent the loop?
