newbie port/pkg question

[Bob Ababurko <ababurko_(_at_)_adelphia_(_dot_)_net>]

hello all-

  coming from using freebsd, I have been used to building my ports.  I 
have just installed OpenBSD 3.5 on my Ultra2 which is very slow at 
compiling, so I am trying to investigate the install of packages.  I have 
downloaded the ports tree onto my box and i notice that there is a ./pkg 
directory inside of the port in question.  How do I use this?  or better 
yet, what is the best way in which I can install the latest package without 
having to know its explicit name/version, eg. bash-2.05b.tgz.  Say, i want 
to install bash....is there a way to install it with out having to go 
through a list of packages to have to find the name/version to only have to 
add it to pkg_add.    Is there a way to do this or somthing similar or am I 
asking for too much. ?

thanks,
Bob
