    I see you're using perl $] on $Config::Config{archname}, 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.

EOT
warn <<EOT if $os eq 'MSWin32';
    Windows users need to use the correct make command.
    That may be nmake or dmake depending on which Perl you are using.
    If using the Win32 ActiveState build then it is recommended that you
    use the ppm utility to fetch and install a prebuilt DBI instead.
