Since this change has only effects on installations where you build and 
install the packages as unprivileged user (and usually don't have access 
to the root account), this cannot be prevented.

But when pkgsrc will finally support building and creating binary 
packages in unprivileged mode, and when these packages can later be 
installed by root, the separation of the user accounts should be done again.
