The DBI package is pure ruby and doesn't depend on any C libraries, so it
installs quite happily. But when you actually try to do
    DBI::connect('dbi:mysql:')  # for example
*then* it will try to instantiate the ruby-mysql package, which is a wrapper
around the mysql C API. If you haven't installed ruby-mysql, then it will
fail.
