I think I'm missing something basic, so if someone could point me
to where that is, I would appreciate it. I been installing
software using portinstall, but I think I'm missing something
basic because there seems to be more guesswork involved that I
expected there to be.

How do you know what name to use for the portinstall to work? For
example, I wanted to install MySQL 41. The folders under
/usr/ports/databases include several variations on my-sql. Among
others are mysql323-server, mysql40-server, mysql41-server, and
mysql50-server. In the Makefile for mysql41 it states PORTNAME?=
mysql. But trying "portinstall mysql" or "portinstall mysql41" or
"portinstall mysql41-server" all result in a message that the
port doesn't exist. The command that works is "portinstall
mysql-server", which I found with a basic google search, but I
don't find that in the descriptions or Makefiles. Looking just at
what is in the ports tree (or anywhere else on a 4.9 system),
where would I properly find that name?
      

  

I was just wondering why you would want to use portinstall to 
install new software, rather than (using your example port):
 cd /usr/ports/databases/mysql-server41
 make install
Is using portinstall magical in some way? If you use the make 
install method, there isn't any guesswork as to what name to use.
    

portinstall is just portupgrade by another name.  Infact, it's pretty
much identical to 'portungrade -f'.  As to why anyone would want to
use portupgrade?  That's a no-brainer.  Just try it and you'll see.

To answer the original question, portupgrade or portinstall can select
a port to operate on in two ways.  You can either give it the package
name -- with or without the version number -- or you can give it the
port origin -- ie. the port directory relative to /usr/ports.  Now,
usually, the first part of package name is the same as the last part
of the port origin, but not always.  For instance the www/apache2 port
installs apache-2.0.52_1.  That similarity of names is what was
confusing the OP.  He could either have issued the command:

    # portinstall mysql-server-4.1.6

or

    # portinstall databases/mysql41-server

and it all would have worked.  The command he did use:

    # portinstall mysql-server

worked for him, but that was partly a matter of luck, as it happened
to default to the 4.1.x branch of MySQL. (Maybe he had
WANT_MYSQL_VER=41 defined in /etc/make.conf or some such -- the
default is to install databases/mysql40-server)

To find out what package name a port will install, just:

    % cd /usr/ports/databases/mysql41-server
    % make -V PKGNAME 

portupgrade processes the /usr/ports/INDEX file into a database of
port origins and package names, which is why you always need an
up-to-date INDEX when using it.

        Cheers,

   Actually, I found the correct entry by searching for "portinstall
   mysql" through google until I found an example that included some
   results other than not found. (WANT_MYSQL_VER was not defined).
