RMySQL installation problem on FC4 x86_64

# yum list installed mysql
Installed Packages
mysql.i386            4.1.11-2               installed
mysql.x86_64       4.1.11-2               installed

I would have thought that you need to have a mysql-dev.x86_64 rpm
package installed in order to get the headers to be able to compile,
etc.  Not a redhat or yum user myself, so don't know.  But the error
message about unable to find header files is often solved by installed
the appropriate devel package that contains those headers.
