This is OpenBSD's fork of Apache 1.3. It runs chroot and privsep'd by default, and of course is patched for security issues where necessary. (OpenBSD recently dropped Apache from the base build and is now fully committed to nginx, moving forward.)
I don't know much about OpenBSD but I know that they upgraded to Apache 2.X only very recently (1 year max IIRC) and it seems that they still maintain the 1.x version: http://openports.se/www/apache-httpd-openbsd
OpenBSD did not upgrade to 2.X. You're talking about ports, which are separate from the base operating system. For accurate information about OpenBSD, right now, check:
Regarding ports, they're basically a compilation build system that complements binary packages (which OpenBSD also has) for 3rd party software not installed with the base system . See:
That someone was mistaken. How exactly do you think they "struggled to maintain" a fork of software that was barely active in the first place? How does "apache but chrooted by default" constitute "frankenapache" exactly? Given that their struggling was so clear to you, could you point me to something that would make it clear to the rest of us?
Why isn't a newer version of Apache included?
The license on newer versions is unacceptable. Users interested in more modern web servers are encouraged to look at nginx(8) which will hopefully be replacing Apache in base.
(the latter has actually happened as of 5.4)
Also the Apache 1.3 in OpenBSD had been audited as it was part of the base distribution (i.e. not just a port) and it ran chrooted by default.
