WARNING: unable to autodetect Apache's MPM <%= PROGRAM_NAME %> has only been tested on Apache with the 'prefork', the 'worker' and the 'event' MPM. However, this installer was not able to automatically figure out the MPM that your Apache was compiled with. This installer tried to autodetect the MPM by running <%= @control_command %> -V, but that command failed for some reason. This may happen if your Apache installation is broken, or if your Apache configuration file has errors. Because at this point this installer is not sure whether your Apache installation is compatible with <%= SHORT_PROGRAM_NAME %>, we recommend that you abort this installer, run the above command and diagnose the problem before continuing. If you cannot figure out what is wrong, please contact the vendor that supplied your Apache installation (e.g. your operating system vendor) for support. Press Ctrl-C to abort this installer (so that you can double-check on things). Press Enter if you want to continue with installation anyway.
