either plug your linux install disc(s) in and search on them, or search from the net (like rpm.pbone.net or rpmfind.net) for the package binutils, or a package containing ld. probably this is your problem, since if you had it installed, you probably shouldn't get that error. I'd say it's the easiest to try and find the package on your install discs, but if you're running a high-speed internet connection and it's not a problem to grab the package from the net, go for it
after you've downloaded the rpm, then do something like
rpm -Uvh binutils-package-name.rpm
where binutils-package-name.rpm is the name of the package you downloaded..if -Uvh doesn't work (you get error or something), read
for instructions. sorry for this, but I don't use rpm so I can't remember it that well...
