This is untrue.  There are two types of Apache modules, and they have
always been handled differently.  Single file modules and multi-file
modules.  

For a single file module, use --with-module=location.  This does work.

For multi-file modules, nobody has added support for those yet.
Regardless, the problem shouldn't be loading already compiled modules.
Rather the problem is with the configure script and getting it to find the
correct files and compile them.  Harrie Hazewinkel wrote a patch against
"./configure" which supports multi-file modules, but it doesn't apply
cleanly because it is against a generated file.  I have been working on
getting multi-file modules to be configured, but I haven't been focusing
on it.

But we already have at least one report of a platform that it doesn't work
on.  We also already have code that does work (it's been working in 1.3.X
for a long time).  I think the biggest complaint about using libtool is
that APR then relies on libtool.  I do not know how other people feel
about that, but I really dislike it.  We have a reliance on one other
library currently, MM.  MM is a part of our tree, and therefore does not
require APR users to go get another library to get things to work.

This is the stumbling block as I see it.  If somebody else sees another
stumbling block, please let me know.
