www-servers/apache-2.4.25::gentoo When installing Apache2 I see the following message: checking whether to enable mod_version... no If I execute: emerge -pv www-servers/apache I don't see an option to compile mod_version as part of the build (i.e. in /etc/portage/package.use/apache). I can compile mod_version if I run the following command: EXTRA_ECONF="--enable-version" emerge www-servers/apache It would be good if mod_version could be added as a use flag.
Add version to your APACHE2_MODULES and recompile, it's in the ebuild (speaking of 2.4.25).
