It's true that libapreq2 is in a development phase, but
it's sufficiently developed that the above basic error
shouldn't occur.

Have you specified, in httpd.conf, to load the module as
   LoadModule apreq_module modules/mod_apreq2.so
(note that it's mod_apreq2.so, not mod_apreq.so). Also, for
Win32, you may need
  LoadFile "/Path/to/libapreq2.dll"
before that to load libapreq2.dll.

If this doesn't help, are you using the mod_perl ppm package
at http://theoryx5.uwinnipeg.ca/ppms/? Earlier mod_perl
versions won't work with the libapreq2 ppm package (from the
same site).

If you have VC++ 6, then, in general, it's probably a good
idea to compile extensions yourself, rather than relying on
binary versions.

Also, I've cc'd the apreq development list, as there may
be people there who can help.
