The recent switch to clang on 10.9 as the reason seemed to make 
sense, as I've run into a similar issue with clang before.  But 
after googling a little bit and looking at the error, maybe the 
problem is a new linker in OS X 10.9?  Assuming we've always been 
passing --export-dynamic to the linker, I don't see why it would 
start failing now, unless the GNU ld from binutils has been 
swapped out.

I suggest you look at where this --export-dynamic flag is being 
added in the build scripts and try changing the number of dashes 
or removing the flag, after looking at the docs for the OS X 
linker to see what flags it takes.
