Which version of tc are you trying to install this on?
"amd-driver-installer-catalyst-13-4-x86.x86_64.run" suggests the 64-bit version of tc, but "i686:lib::none:3.0.21-ti" suggests the 32-bit version.
On my hardware (macmini), I don't require any any additional drivers for to connect a monitor via the hdmi output, albeit connected via an hdmi-dvi adapter.
