Module::Build is recommended (but not necessary).
  Install Module::Build now from CPAN? [y|n] y|n
Sorry, we have to rerun the configuration dialog for CPAN.pm due to
some missing parameters...

Do you want to use a different command for './Build install'? Sudo
users will probably prefer:

    su root -c ./Build
 or
    sudo ./Build
 or
    /path1/to/sudo -u admin_account ./Build

 <mbuild_install_build_command>
or some such. Your choice: [./Build] ./Build



Please remember to call 'o conf commit' to make the config permanent!
