Cool. I think the patch should look like the one below, then.

Just to double-check that I have explained the issue correctly, can you
share the output of "apache2 -l"? Mine has:

  $ apache2 -l
  Compiled in modules:
    core.c
    mod_log_config.c
    mod_logio.c
    mod_version.c
    prefork.c
    http_core.c
    mod_so.c

which explains why it works here. I'm assuming you will not have
mod_version.c compiled in.

Subject: lib-httpd/apache.conf: check version only after mod_version loads

Commit 0442743 introduced an <IfVersion> directive near the
top of the apache config file. However, at that point we
have not yet checked for and loaded the mod_version module.
This means that the directive will behave oddly if
mod_version is dynamically loaded, failing to match when it
should.

We can fix this by moving the whole block below the
LoadModule directive for mod_version.
