Hi,
  I'm not an expert, but I would recommend re-installing binutils, gcc and then 
avrlibc. Personnally, what I do is that I specify a different prefix for each 
installation that I do. For exemple, "/usr/avr-gcc-3.4.2" for my gcc-3.4.2 
installation and "/usr/avr-gcc-4.1.0" for my gcc-4.1.0 installation. Then, I 
create a symbolic link "/usr/avr --> /usr/avr-gcc-4.1.0". This way, I can go 
back to previous compiler versions in case I need to.

  Hope this help. Hugo
