Because Alien::MeCab may have been called to be installed from a dependency
of another module, we want to make sure that you *really* want to install
this version of Alien::MeCab (and therefore libmecab).

If you answer "y", then We're going to install
    libmecab: $MECAB_VERSION

This operation may OVERWRITE your previous installation
