I downloaded gmp 5.0.1, did a ./configure --prefix=/usr/local/ , then did a
make and make install and that worked fine. I also installed mpfr 3.0.1 and mpc
0.9 the same way. Do you need all 3? I'm not sure, but that got rid of that
issue.

I installed binutils 2.21 using the instructions here:
http://www.nongnu.org/avr-libc/user-manual/install_tools.html#install_avr_binutils
I didn't install any patches from the MHV guys, but the only ones I have don't
seem very relevant. The MHV tools are using 2.20.1, so I'll try that version
and installing the patches next.
Thanks.
