Unfortunately, you've just run into one of the pitfalls of installing stock 
programs. I just looked at the port of mysql-server and there are no less 
than 10 patches (most dealing with configuration) not counting the ones in 
mysql-client. Unless you're willing to spend the time dealing with all that 
by hand you're better off uninstalling and using the package version of that 
port. Installing a package is very easy and documented in the handbook. Other 
than that you need to take a close look at configure in the sources and you 
may need to adjust those for your system. In the short term what you have is 
a file permission problem. Find out what user mysql is trying to run as (most 
likely "mysql"), make sure that user exists and set your file permissions on 
the mysql directory to allow it to write as that user. It's ok to 
use "adduser" to create the user.
