The databases/mysql80-server port installs a file /usr/local/LICENSE.router. Please fix the port to either install the file in a port specific location or not at all (since another LICENSE file is installed in the correct place).
There is also /usr/local/README.router
Created attachment 235658 [details] Fixed databases/mysql80-server/files/patch-cmake_install_layout.cmake The patch databases/mysql80-server/files/patch-cmake_install_layout.cmake needs to set INSTALL_DOCREADMEDIR_FREEBSD to "docs" instead of "." Fixed patch attached
BTW This patch should also go upstream for inclusion, as it was forgoten at the time (MySQL 5.6/5.7) as the FREEBSD Layout got upstream.
