Try...
in apache directory
make distclean
./configure --with-layout=Apache
then
in mod perl source directory
Run:
perl Makefile.PL \
APACHE_SRC=/usr/src/apache/src \
DO_HTTPD=1 \
USE_APACI=1 \
PREP_HTTPD=1 \
EVERYTHING=1 \
make
make test # broken ??
make install
back in apache directory
./configure --with-layout=Apache \
--activate-module=src/modules/perl/libperl.a
make
make install
