I dont know why my Radeon X800 won't run right. I am not getting any 3D acceleration. I have the right driver i think because my system recognized it... i am running FC3 64... if anyone can help, let me know

When I try to install the 64 bit driver, i get this error
Code:
rpm -ivh fglrx64_6_8_0-8.10.19-1.x86_64.rpm
error: Failed dependencies:
libstdc++.so.5()(64bit) is needed by fglrx64_6_8_0-8.10.19-1.x86_64
libstdc++.so.5(CXXABI_1.2)(64bit) is needed by fglrx64_6_8_0-8.10.19-1.x86_64
libstdc++.so.5(GLIBCPP_3.2)(64bit) is needed by fglrx64_6_8_0-8.10.19-1.x86_64
How would i attain these dependencies?
