Looks good

    I see you're using perl 5.040000 on x86_64-linux, okay.
    Remember to actually *read* the README file!
    Use  'make' to build the software (dmake or nmake on Windows).
    Then 'make test' to execute self tests.
    Then 'make install' to install the DBI and then delete this working
    directory before unpacking and building any DBD::* drivers.
