I want to add mod_proxy and mod_proxy_http to Apache server on my Gentoo, but apparently some file with high priority on the system is disabling the mods and preventing me to install. I am currently editing /usr/portage/profiles/base/make.defaults file, but it gets updated (and changes lost) every time I update the system. I have to edit it every time I update the system/reinstall Apache. Besides that, I have already added dependencies to the /etc/portage/package.use file: www-servers/apache proxy proxy_http What other files do I have do change or should check flags so I can enable proxy and do not have to edit files again every time?
