Any reason not to combine rb-mysql & rb-mysql5?

Ok, I'll do it.  But the combined one will support mysql5 by default and
mysql4 with a variant, so a future rb-mysql5 shouldn't be needed.  Of
course, the only way to specify that you use mysql4 would be 'port install
rb-mysql +mysql4', because a port can't specify a dependent's variants,
but we have to deal with that with all our other ports too.  

By the way, should rb-dbd-mysql be upgraded from 0.0.23 to 0.1.1, the
latest?  Or is there some reason it needs to stay at the older rev? 
Thanks.
