I have done the trusting part automated on my linux box like the following.
Give a try anyways and let me know whether it was helpful or not. I did many
google search and could not find any method described for this. The
following method worked gr8 for me and is the one which I created myself

For trusting it as 3, use 4 and for 5, use 6 and so on...

   1. gpg --import - Import your key
   2. echo $(gpg --list-keys --with-fingerprint --with-colons | tail -2 |
   head -1 | tr -s ":" ":"| cut -d ":" -f2):4: > /tmp/somefile1 - take the
   finger print and copy to a temp file.
   3.  gpg --import-ownertrust < /tmp/somefile1 - import the finger print to
   the trust data base. Done!!!!

You can check the trusting part by typing the below command

   1.  gpg --export-ownertrust
