Where to get what? binutils?
Well, if it isnt updating through yum, try force updating it.
I'm assuming you're on an i386 based cpu here
You'd want the one that looks like this obviously
Fedora Core 4 for i386 binutils-188.8.131.52.2.2-2.i386.rpm
Download that, and upgrade the current install of binutils
rpm -Uvh binutils-184.108.40.206.2.2-2.i386.rpm
Should have the latest version after that.
