Please cvsup your ports tree, there is a patch to solve this problem for quite 
some time. (files/patch-ac)

This is not the right way to fix this problem, in my opinion.

Not sure where this is coming from, but your analysis seems to be correct.  
Did you try to use "-6"?

Try the cvsup, this might already fix your problem.  If not, ping me back.  
BTW, I am a graduate student at University of Karlsruhe.
