[R-SIG-Mac] RMySQL problem

Answered my own question:  Installing RMySQL from source did make the  
warning go away and restored all functionality (although dbWriteTable  
worked in my last message, dbReadTable still crashed R).  The Package  
Installer menu item was all I used for the Source install (viewing  
CRAN "source" packages, then Install).  It was not necessary to  
install DBI from source.
