It could well be that urpmi is looking straight at the device /dev/hdc, rather than looking at /mnt/.... or wherever. If this is the case, then it's never going to work except by burning a CD and sticking it in /dev/hdc.
However, just check the output from mount that the 3 /mnt entries you mention are actually mounted, the permissions are right, and that you can browse them.
As a last resort, you could always locate libpcap and tcpdump yourself and install the 3 rpms by hand using rpm.
