Help getting started

[Steve Lustbader <sbl_(_at_)_MIT_(_dot_)_EDU>]

I just installed OpenBSD 3.0, and I'm trying to set it up as a web 
server.  I installed mysql and PHP 4.06 (from packages).  I want to patch 
or upgrade PHP to avoid the vulnerabilities that were just publicized, but 
I don't know how.  Basically, I'm looking for hand-holding or a HOW-TO for 
upgrading/patching things installed from ports or packages.  Do I have to 
scrap the installed version to upgrade?  If I download the source and make 
it, is that all I have to do (ie does everything end up in the right place, 
etc)?  Also, how do I check the version of installed programs (like Apache 
or OpenSSH)?  Any general help would be really appreciated, too.

Thanks,
Steve
