upgrading to conflicting dependencies

[Daniel Horwood]

gnucash depends on the goffice03 port (and is the only port in the  
tree that does), but can now work with the newer goffice port.

I've made a patch on http://trac.macosforge.org/projects/macports/ticket/14893 
  that changes the gnucash dependency to goffice, but the problem is  
that goffice conflicts with goffice03.

What's the best way to solve this problem? I thought about  
deactivating goffice03 in the gnucash portfile, but that won't work  
because MacPorts will try to install the dependencies (ie goffice)  
first.

Can the goffice03 portfile be "redirected" to goffice? (I guess this  
is a bit like the scrollkeeper->rarian change).

Ideas?
