You should not "compile in" any MPM, compile them all as modules and
load one in configuration. That just reveals you probably didn't use
"--enable-mpms-shared"
As per configure script help:
--with-mpm=MPM Choose the process model for Apache to use by
default. MPM={event|worker|prefork|winnt} This will
be statically linked as the only available MPM
unless --enable-mpms-shared is also specified.
Try again with something like:
--enable-mpms-shared=all --with-mpm=event
Issue a "make clean" first if necessary.
