With this patch, my test run starts like so:

    rm -f -r 'test-results'
    *** prove ***
    apache2: Could not open configuration file /etc/apache2/apache2.conf: No such file or directory
    ...

I find the error message leaking mildly annoying, and would suggest
doing something like the following on top.

diff --git c/t/lib-httpd.sh w/t/lib-httpd.sh
