Independent of the version number of MySQL (which is less than 6 months 
If you are talking about the RMySQL binary build on CRAN: It is build 
against a 32-bit version of MySQL. I am not sure if there is a safe way 
to build a binary that properly links against 64-bit MySQL given you are 
running 32-bit R.
If there is, you have to install the package from sources yourself anyway.
