Thanks!

That is interesting, how would I, were I to make this variant for the port, know the value to put for --with-dlz-mysql?

If I go to the driver page for DLZ http://bind-dlz.sourceforge.net/mysql_driver.html
I see this mention:

    The configure script will search in the normal locations for the 
    MySQL headers and libraries. You can specify the appropriate 
    directory if it is not found by appending a path to the MySQL 
    configure option. For example: --with-dlz-mysql=/path/to/files

    To find out where your mysql headers and libraries are you can run 
    the mysql_config command. "mysql_config --cflags" will return the 
    path to the MySQL header files, and "mysql_config --libs" will return 
    the path to the MySQL library files.

That leads me to believe that I am looking to put in the returned output from the mysql_config(5) command, not the path to the actual file.  Is that perhaps bad/misleading instructions on the part of the driver docs?  It even says it will search a path, but to me, it seems like it is calling the command, and searching the paths in the results of that command, which is entirely different from the statement in the docs.

I sat here and tried multiple times using the output of /opt/local/bin/mysql_config5 --cflags and --libs to now know which of the two to use, and within each of the two, which of the few results to use.  I seem to run into this often in ports I am working on that are not run of the mill just work out of the box ./configure and that is all there is too it type of software. Usually all I ever have to do is enter in a prefix value and maybe a man page path, outside of that, I run into small stumbling blocks such as this.

Thank you for any clarifications.
