Jim Morris noted this on OpenBSD in May for Subversion 1.2.0:
http://subversion.tigris.org/servlets/ReadMsg?list=dev&msgNo=100686
My attached patch differs from his that users must explicitely
enable IPv6 if they want svnserve to listen on an IPv6 socket. It passes
the svncheck and svncheck6 (using --ipv6) on OpenBSD/i386 -current.
Existing IPv6 users of svnserve have to add --ipv6 as option to
svnserve, so for them this patch is a regression.

Various platforms has different level of support for IPv6, as may be
seen in posts to dev@. A fix for one OS may very well result in
broken code on another OS.
It has been suggested it may be an apr issue, or the way apr is used.
As far as I know, the approved version is still 0.95.5, but the package
maintainers are likely to use already installed apr/apr-util instead
of the one in the subversion tarball. The version of installed apr will
differ from OS to OS.
I want to avoid creating new issues by making a fix to svnserve that
depends on which version of apr is used, or just happens to work on my OS
of choice.
My patch seems safe in this regard.
