on upgrade 1.4.5->1.5.0, cannot load mod_dav_svn.so (with solution)

I ran into an issue when upgrading my server from subversion 1.4.5 to

I was using Apache 2.2.3 with OpenSSL on Windows Server 2003 SP2.

I replaced my clean binary build of 1.4.5 with a clean binary build of
1.5.0. After doing so, httpd would fail to start with the following
error in the Application Log:

Event Type: Error
Event Source: Apache Service
Event Category: None
Event ID: 3299
Date: 04-Jul-2008
Time: 20:24:56
User: N/A
Computer: MESSIAH
The Apache service named reported the following error:
>>> httpd.exe: Syntax error on line 486 of C:/apache/conf/httpd.conf:
Syntax error on line 1 of C:/apache/conf.d/svn.conf: Cannot load
C:/svn/bin/mod_dav_svn.so into server: The specified procedure could not
be found. .

For more information, see Help and Support Center at

Note that the error is different from the FAQ entry
(http://subversion.tigris.org/faq.html#mod_dav_svn-win32). The FAQ
entry addresses that "the module could not be loaded", not that "the
procedure could not be found".

I replaced Apache 2.2.3 with Apache 2.2.9 (also with SSL), installed the
Visual Studio 2008 redistributable dependency, and then httpd was able
to start and serve Subversion 1.5.0.

I suspect the issue was related to the older SSL libraries in Apache
(0.9.8d) not having the correct entry points.

Since I did not see anything on my searches about this error message, I
wanted to report my findings here in case anyone else encounters the

Cheers on the 1.5.0 release.
