The currently stable apache-2.4.34-r1 does not start. It fails at startup with the following line output to the terminal: apache2: Syntax error on line 116 of /etc/apache2/httpd.conf: Cannot load modules/mod_lbmethod_byrequests.so into server: /usr/lib64/apache2/modules/mod_lbmethod_byrequests.so: undefined symbol: ap_proxy_balancer_get_best_worker This thread in the forums was the genesis for this bug: https://forums.gentoo.org/viewtopic-t-1084990-highlight-apache.html This post on serverfault appears to demonstrate that it's an upstream issue with module load order: https://serverfault.com/questions/922573/apache2-fails-to-start-after-recent-update-to-2-4-34-no-clue-why # emerge --info www-servers/apache fatal: Not a git repository (or any parent up to mount point /usr) Stopping at filesystem boundary (GIT_DISCOVERY_ACROSS_FILESYSTEM not set).

I do not consider this one fixed completely. With the upstream patch it now fails with "mod_proxy must be loaded for mod_lbmethod_..." when the lbmethod USE flags have been activated and the modules loaded unconditionally, but -D PROXY is not added to APACHE2_OPTS. I think we should move all lbmethods to the PROXY define.
