Disclaimer: this bug has been filed in a semi-automated manner. When emerging the package app-text/libpaper-1.1.24-r1, the following elog messages are displayed: * run "paperconf -p letter" as root to use letter-pagesizes * or paperconf with normal user privileges. Such messages should only be displayed when the package is a new install. These situations can be checked in the ebuild as follows: if ! has_version 'app-text/libpaper'; then See the tracker bug 440214 for more details.
Done, thanks.
