I was under the impression that doing this within the pre-fetch phase  
was acceptable. I thought we discussed this on the list earlier. Many  
ports do this: xorg, wine, mozilla, sockstat, ipcs, gauche-gtk,  
mysql5-devel, TeXShop.

If that's not ok, then we really do need someone to implement  
ui_fatal. But what would that do differently?

There are some ports that still do it directly in a platform  
selector: xloops, nestedsums, cln, GiNaC, hugs98, ghc, klisp,  
kdelibs3. I can see how that's indeed wrong and needs to be changed.
