Disclaimer: this bug has been filed in a semi-automated manner. When emerging the package app-editors/vim-7.3.409, the following elog messages are displayed: * The 'X' USE flag enables vim <-> X communication, like * updating the xterm titlebar. It does not install a GUI. * To install a GUI version of vim, use the app-editors/gvim * package. Such messages should only be displayed when the package is a new install, or when the relevant USE flag is not enabled in the current installed version. These situations can be checked in the ebuild as follows: if use X && ! has_version 'app-editors/vim[X]'; then See the tracker bug 440214 for more details.
Fixed in current versions.
