Mmm… I didn’t expect to have these troubles getting Apache 2.2.0 to run on FreeBSD. At first, I couldn’t even get it to build because it failed fetching an image (gif) file. So I updated the ports collection and luckely this did the trick. The rest of the install went fine but I couldn’t get the daemon to run. Checking the logs I noticed configuration failed on mod_unique with:
[alert] (EAI #) hostname nor servname provided, or not known: mod_unique_id: unable to find IPv4 address of ####
After a quick search google came up with this and the suggestion to comment out the mod_unique line in httpd.conf also did the trick for me.
