What System do you have currently? 10.0 or 10.1?
10.0 has: libbfd-2.16.91.0.2.so
10.1 has: libbfd-2.16.91.0.5.so
This subtle difference is why you can't mix packages - it's not possible, the libraries are not compatible.
The one you just tried to install is for 10.0 and will not work on 10.1. For the one I built for 10.1, you have to install the binutils package first, this will give you libbfd-2.16.91.0.5.so, and then aMule.
