Would this consist of:

1.  First doing a portupgrade?  (OS is FreeBSD 4.4, ports are 
    pretty much that old.)

    # portupgrade gnupg -arR

    (The -R will check the build dependencies and the -r 
     will check the applications that depend upon the 
     port being upgraded. This will prevent your system from having
     outdated dependencies and software incompatibilities.)

    (Would I need to be logged in as root, or would a super user
     be fine?)


2.  Go to:
    # cd /usr/ports/security/gnupg

3.  # make

4.  # make install

5.  # make clean

6.  Would I need to reboot to have full functionality?  (This is
    a production server, so this process would need to be done
    during off hours.)

    Like this?

    # gpg --gen-key

   Something like these?

>5) Profit!

    Could you be *VERY* specific on how to do this?  ;^)



Thanks!
