Configure apache 1.3 like this:
./configure \
“–with-layout=Apache” \
“–enable-module=most” \
“–enable-shared=max” \
“–enable-module=so” \
“–enable-shared=ssl” \
“–enable-rule=EAPI” \
“$@”
Leave off SSL + EAPI if you are not using SSL.
This will enable and compile all of the DSO modules and put them in Libexec.
