I thought I had them both working, but maybe my mind's playing tricks on me. I accidentally deleted /usr/local/include on my new production server (that I'm still building). I rebuilt it successfully by rebuilding all the ports and filling in the blanks with a tarball of the same dir on my experimental server, which I had built with the same commands. I have been getting all sorts of errors trying to run either "mysql" or "/usr/local/bin/mysqld_safe &", the latter giving more feedback and the former complaining about a socket binding problem (" Can't connect to local MySQL server through socket '/tmp/mysql.sock'"). However, when I went to try the same commands on my experimental server, much to my surprise I got the exact same errors! The only thing I did to that server was run a tar -cvf

cannot make heads or tails of what you're trying to say.  All I can
make out is that when you bring up mysqld, it doesn't stay up, thus
mysql and other applications that try to talk to the MySQL server
cannot, since it's not running.

The fact that you broke /usr/local/include is probably not a good
thing either.  Have you considered doing something like pkg_info,
making a list of all the packages you have installed, doing
pkg_delete -a -f && rm -fr /var/db/ports/*, then reinstalling all of
the ports in question?

Are you _building_ MySQL or are you using the package (pre-compiled
binary package)?  What version of MySQL are you choosing to use?

What exactly is in your my.cnf?  This looks suspicious.

There is no such table "general_log" in database "mysql" in MySQL
4.0 nor 4.1.  errno 13 is Permission denied, by the way.  So how is
this table getting loaded?

Maybe this table exists in the beta (5.0), but I choose not to use
that for obvious reasons.

This also looks indicative of a permissions problem with your
/var/db/mysql directory.  The directory should be identical in
ownership and permissions to this:

drwx------    7 mysql     mysql     512 26 Feb 09:46 /var/db/mysql/

Ensure that all underlying directories and files are also as such
(ownership/group; permissions don't matter so much, other than
executable on directories, obviously).

Another example of a permissions problem, and this is why mysqld
won't start, thus why your applications say they can't talk to
mysql via /tmp/mysql.sock and what not.
