Apache segfault on startup

Hi all,

I built Apache 2.2.3 from tarball, and it is installed in
/usr/local/apache2. I downloaded the svn 1.4.2 tarball, and configure
reports the right path:

...
checking for Apache module support via DSO through APXS... found at
/usr/local/apache2/bin/apxs
checking httpd version... recent enough
configure: Apache Portable Runtime (APR) library configuration
checking for APR... yes
checking APR version... 0.9.7
configure: Apache Portable Runtime Utility (APRUTIL) library configuration
checking for APR-util... yes
checking APR-UTIL version... 0.9.7
...
## ----------------- ##
## Output variables. ##
## ----------------- ##

APACHE_INCLUDES=' -I/usr/local/apache2//include'
APACHE_LDFLAGS=''
APACHE_LIBEXECDIR='/usr/local/apache2//modules'
APACHE_TARGET=''
APXS='/usr/local/apache2/bin/apxs'
...

Yet, when I enable mod_dav_svn and mod_authz_svn, Apache segfaults
immediately on startup:
[Wed Dec 13 16:31:55 2006] [notice] child pid 25082 exit signal
Segmentation fault (11)

I know I made a mistake somewhere. I just don't know what it is.

My Apache configure:
./configure --disable-include --disable-dir \
  --enable-dav --enable-deflate \
  --enable-proxy --enable-proxy-balancer \
  --disable-userdir --with-ssl \
  --with-z --prefix=/usr/local/apache2/

And Subversion's:
./configure --prefix=/usr/local

I did find a variety of messages on dev@svn essentially saying "check
that svn builds against the right version of Apache". So my question
really boils down to: how to do that ?

Thanks !
