This might sound stupid, but I actually don't know. What I did was to do a
"make install PREFIX=/usr/opt" in the /usr/ports/security/gnupg directory to
add the port to our system.
After completion, I simply tried to use the tool to generate key. "gpg
--gen-key" I belive it is (not at the job right now). I tried big and small
sizes of the key and the all hanged after informing me that there wasn't
enough entropy and that I needed to work with the keyboard to generate some more.
So, this might be an answer to at least the gnupg problem. How do I
instruct/make gpg select /dev/random instead?
