libzdb help!

[Bradley Giesbrecht]

libzdb does nothing without one of the three supported dbs installed.

And know one will probably want it unless they are already installing  
something else that needs it.

But if I add it as a dependancy to dbmail-devel (I'm porting this now)  
and dbmail-devel needs one of the same three db's I could maybe just  
combine the two distributions and configure libzdb for what ever db  
backend variants were chosen for dbmail-devel?

Because if I just add libzdb as a dependancy for dbmail-devel I won't  
have control over variant's for libzdb. Right?

That's why I was thinking of just letting libzdb find the available  
db's on it's own since at least one of the db's variants in dbmail- 
devel MUST be chosen so there will always be at least one.
