Please Install the Updated Packages.

The version of nmap shipped with Mandriva Linux 2007 was built against the system copies of the libpcap and libdnet libraries. However, nmap actually requires changes to be made to these libraries which have not yet been made to the upstream versions, and consequently should be compiled against its own built-in copies of these libraries. This problem causes nmap not to work as the root user: it would simply freeze up. The updated package fixes this problem. It also fixes the menu entry for the package.
