I am lucky and am now working with a new Redhat Linux 64-bit OS

But I am getting the following error can anyone provide some graciously
needed assistance:


[root at bluebird system-files]# rpm -i R-2.8.1-1.rh5.x86_64.rpm
warning: R-2.8.1-1.rh5.x86_64.rpm: Header V3 DSA signature: NOKEY, key ID
99b62126
error: Failed dependencies:
        xdg-utils is needed by R-2.8.1-1.rh5.x86_64



Thanks
Steve
