Dear Kjell,

As you can see above, your R port on Macports appears to be broken and  
has a reputation of having been broken for a while. I for one have  
experienced odd problems as described above. To avoid further issues  
with unsuspecting Macports users, perhaps it would be good to pull the  
port from the repository until a decent level of reliability can be  
provided ?
