  On modern Unix derivatives there exists a nifty mechanism usually called
  dynamic linking/loading of Dynamic Shared Objects (DSO) which provides a
  way to build a piece of program code in a special format for loading it
  at run-time into the address space of an executable program.

Under Apache, this lets you use LoadModule to pull in modules when you
start your httpd.

    ^^^^^^^^

This module loads DSO's.

If you had mod_perl built statically ("apache compiled with mod_perl"),
you would see mod_perl.c on that list, like:

$ ./httpd -l
Compiled-in modules:
  http_core.c
  mod_perl.c
  mod_so.c
