Dear Pat


i really thank you for taking time to answer other user's questions, but
i think you are really wrong.

I will insist, the check is to see if the installed version complies
with the package's requirements.

As I understand the <check /> does not have any inference in the
decision of upgrading or downgrading a package.


I would like to have some other users to give her thoughts on this.
