This is certainly a possibility. I believe that a GHC built against  
MacPorts would work properly on a system with MacPorts installed.  
However, the downside of that approach is that any binary compiled  
with such a GHC could _only_ be run on a system with MacPorts installed.

I'd love to have a GHC that would play nicely with MacPorts, but not  
depend on it unless necessary (where "necessary" means "when I use a  
package that links to a C library only available via MacPorts")
