In step 6, the command should be

./configure --with-apxs=/usr/bin/apxs2

but not ./configure --with-apxs2=/usr/bin/apxs2

I've tried using the second one and ended in some very needless confusion down the road: "./configure" wasn't finished successfully with the the second one and complained that the "webserver" (parameter) is missing. But that should not be the case because we are configuring for a shared library, not a static one.
