Try my toolchain builder. It is part of my os (smaller as TinyOS!) for 
the avr.

It downloads, patches and builds the tools for you. Versions are  
utils:2.19, gcc:4.3.3,  gmp:4.2.4, mpfr:2.4.0, libc:1.6.4, dude:5.5.
It has been tested for gentoo, ubuntu, fedora8, osx, 
windows2000/2003 and  windowsXP (with cygwin). You can find 
the  package here:

 http://www.femtoos.org/
 via code | download

or directly via:

  http://sourceforge.net/project/showfiles.php?group_id=219072

Usage is simple, but read the "readme" !!
And the under cygwin, the script may run for more than two hours,
so be patient, even if the progress indicator does not update,
and indicates < ? > for a (long while).

Jus for the record, for Ubuntu 8.10 , you may need to insert
 --disable-werror CFLAGS="-Wno-format-security "
after --with-dwarf2 in the script where the binutils are build. 
Line 585 of the script. (This was an idea of bingo, see
  http://www.avrfreaks.net/index.php?name=PNphpBB2&file=viewtopic&t=72619 )

Good luck!
