To the best of my knowledge, this is harmless and can be ignored.  
Linking continues after this message is printed, and I haven't yet  
found any adverse side-effects.

The message is triggered (in Apple's recently-rewritten linker) when  
there are two or more labels pointing to the very end of a section in  
an object file. This sometimes happens when empty _closure_tbls are  
emitted by GHC; it's probably not too hard to prevent this from  
happening.

Cheers,
