You can get the sources from Apple and compile it:
http://www.opensource.apple.com/darwinsource/tarballs/other/libiconv-13.2.tar.gz

If you want to save yourself the hassle, my 64-bit build can be  
obtained and installed as follows:
curl -s http://r.research.att.com/libiconv-quad.tar.gz | \
sudo tar fvxz - -C /usr/lib

Given that it's compiled from Apple sources, it should be identical to  
the system binary (except that it's not stripped).

However, if you feel more comfortable just adding the 64-bit part to  
your system's iconv, you can do so by unpacking my version and using  
lipo to extract the x86_64 part and lipo again to add it to /usr/lib/ 
liviconv.2.dylib

Cheers,
Simon
