problem s nmapem

[Jaroslav Votruba]

chtel jsem nainstalovat novejsi verzi z portu, ale prej musim nejdriv 
odinstalovat starsi verzi. Bohuzel nevim jak, kdyz v portech tato starsi 
verze neni a nevim jak se ji zbavit. na trvdku bych jej nerad prepisoval.

===>  Installing for nmap-4.62
===>   Generating temporary packing list
===>  Checking if security/nmap already installed
===>   An older version of security/nmap is already installed (nmap-4.20_1)
      You may wish to ``make deinstall'' and install this port again
      by ``make reinstall'' to upgrade it properly.
      If you really wish to overwrite the old port of security/nmap
      without deleting it first, set the variable "FORCE_PKG_REGISTER"
      in your environment or the "make install" command line.
