 	Firstly, thanks for testing the port. I really appreciate it.

 	If you are using the base compiler, this is probably normal. During the 
 ./configure of the compiler, it either searches for or is told where to find 
 ar, as, ld, etc.. You can override this by setting the appropriate environment 
 variables either in your environment or in the /etc/make.conf: 
 AR=/usr/local/bin/ar, etc. To be honest, using the new binutils with the base 
 compiler really wont do very much for you, its useful if you also upgrade your 
 compiler (to take advantage of processor features that the base tools are not 
 aware of yet, IE: SSE4)
 
 	What you might consider is building /usr/ports/lang/gcc43. When this port 
 configures, it will find the new tools and use them by default. 
 
 	The above is the path I took, and in addition, I added the following to my 
 /etc/make.conf to use it by default:
 
 <in /etc/make.conf>
 #CFLAGS= -O2 -fno-strict-aliasing -pipe -s
 #CXXFLAGS+= -fconserve-space
 
 CFLAGS= -march=native  -O2  -fno-strict-aliasing -pipe -s
 CXXFLAGS+= -fconserve-space
 CC=gcc43
 CXX=g++43
 NO_CPU_CFLAGS=         # Don't add -march=<cpu> to CFLAGS automatically
 NO_CPU_COPTFLAGS=      # Don't add -march=<cpu> to COPTFLAGS automatically
 
 	Now I comment out the first block when I am compiling from the ports tree, 
 and comment out the second block (and uncomment the first) when compiling the 
 world and kernel. Just be aware that using the later gcc will break many of 
 the ports due to gcc's Header dependency cleanup. So, if you find something 
 that is broken, just switch back to the first block and try again.
