The reason it then still doesn't work is because libzdb is calling  
mysql_config incorrectly. As you note, it uses "mysql_config --libs  
$LDFLAGS". It is not correct to put "$LDFLAGS" at the end of that  
command invocation. The correct way to call it is just "mysql_config  
--libs". It works for you on the command line because LDFLAGS is  
empty by default, but MacPorts fills it with a value, so when run  
within MacPorts, it fails. If you look in the config.log, you see  
that mysql_config is printing its usage message, showing that the way  
it is being used is not correct. Attached is a Portfile and patch  
that work for me. You should send the patchfile to the author of libzdb.

In the Portfile, I also added a dependency on mysql5, and added  
configure arguments to disable postgresql and sqlite. If you want to  
enable postgresql or sqlite, remove the corresponding configure  
argument and add the required dependency.
