    I know this is a different issue, and being hashed in another thread, 
but this is exactly what I did. However, with an older version of binutils 
installed, I didnt get the advantage of being able to use SSE4.1 on my 
machine. I made from the sources binutils, but it was a real pain to get the 
/usr/ports/lang/gcc/gcc43 port to pick up the presence of the newer version 
of binutils. I had to make simlinks for various directories and every time 
they changed the port it would klobber the links. It became ickey!
