[clue] [Tech] Apache apxs

[Mike Staver]

I agree compiling Apache isn't that big of a deal, but I currently have
this machine wearing many different hats:

1) Mail server.
2) Standard Apache box with multiple apache vhosts.
3) Subversion box, via Apache of course.
4) Bind server.
5) Samba LAN file server.

Upgrading this machine will take some careful planning :) I currently have
the following installed:

[root at server ~]# rpm -qa | grep httpd
httpd-suexec-2.0.52-47.ent.centos4
httpd-2.0.52-47.ent.centos4
httpd-devel-2.0.52-47.ent.centos4
system-config-httpd-1.3.1-1
httpd-manual-2.0.52-47.ent.centos4

I'm bummed that I can't figure out a way around this without recompiling,
because having updated versions of software delivered automagically with
update commands is much easier than compiling an update everytime Apache
puts one out, which is more often than I would like to worry about it.
