SOLVED: Unsupported RA plugin ABI version (2) for ra_dav.

OK, figured this one out. Apparently, if I try to build WITH dav support but
WITHOUT a copy of neon, the build process decides to use the following

1. Print a one-line inconspicious warning about neon missing, which would
result in DAV support being excluded (never mind that I asked for it to be
2. CONTINUE to build without DAV support.
3. Leave me with seemingly working build.

Please tell me this was intended to be that way in order to serve as an
initiation rite for anyone joining in on SVN development. :-)))

Seriously, I'll see if I can hack the autoconf stuff to fail if the above
condition is met. However, it would still make sense to make SVN work without
ra_dav for local access.
