I had found this problem quite a while ago and had submitted a spec file that
fixed the problem at least for me. It seems that when apache2 is compiled
with --disable-shared it creates a libtool that has "build_libtool_libs=no"
and that is what was causing my problems.
I had added the following to the "install" section:
%if "%{with_shared_core}" == "yes"
%{l_shtool} subst \
-e 's;^build_libtool_libs=no;build_libtool_libs=yes;' \
$RPM_BUILD_ROOT%{l_prefix}/share/apache2/build/libtool
%endif
Looking at the apache2.spec in the sources that is still in there. I am able
to compile mod_dav_svn, mod_php, mod_suphp, and mod_pubcookie as shared
modules with that configuration. It is possible that none of those modules
use apxs directly and use %{l_prefix}/share/apache2/build/libtool to build
the module instead.
I even submitted a bug report to the apache project, because this used to work
just fine in apache 1.3.x. I just got a response that said this was by design
and that was it.
