If you have database variants in dbmail-devel, then put those same  
variants into libzdb. When a user installs dbmail-devel with one of  
those variants, if libzdb was not already installed, MacPorts will  
pass those variant selections to libzdb and it will be installed with  
the same variants. There is a potential problem if libzdb was already  
installed with a different set of variants, but that can perhaps be  
addressed later.
