I just finished migrating my deploy script from Capistrano 1.4.1 and
Deprec 1.9.2 combo to Capistrano 2.5.0 with a lot of help from Lee
(thank you sir). It is working great. However, there is one thing
that I do not understand. It always gives this line of error message
when I run it initially with seemingly no ill effect. Every
subsequent run is clean until I have to type in the password again.
Here is a snippet of Capistrano session:

I do not claim any originality for this script, only creative merging
from various sources. Feel free to use it in your own work. But
kindly critique it so that I can improve it and learn.
Also, please point out why I get this error message, I do not
understand it.
Thanks.
