how to configure apache 2.0.35 with "--enable-mods-shared=most"

[cyan01]

As root, I did the following:

root@tbird 70 %> ./configure --enable-mods-shared=most --prefix=/usr/tomcat/apache_source_withMod
root@tbird 71 %> make
root@tbird 72 %> make install
root@tbird 73 %> cd /usr/tomcat/apache_source_withMod/modules
root@tbird 74 %> ls -l
total 5762

So I made sure that most modules were installed as expected.

However, I can not invoke apache:

root@tbird 75 %> /usr/tomcat/apache_source_withMod/bin/apachectl start

(125)Address already in use: make_sock: could not bind to address [::]:80
no listening sockets available, shutting down
./apachectl start: httpd could not be started


Can someone please explain it to me?

Many thanks!
