Undefined symbols: svn_ra_*__init

I have a feeling I'm just missing something obvious, but here goes anyway...

I haven't built Subversion from trunk in a while, but I just tried with
gcc 3.4.4 on Linux. After running autogen.sh and configure
--enable-maintainer-mode on a fresh checkout of the trunk, I get the
following errors while linking the cmdline client:

../../../subversion/libsvn_ra/.libs/libsvn_ra-1.so: undefined reference
to `svn_ra_local__init'
../../../subversion/libsvn_ra/.libs/libsvn_ra-1.so: undefined reference
to `svn_ra_dav__init'
../../../subversion/libsvn_ra/.libs/libsvn_ra-1.so: undefined reference
to `svn_ra_svn__init'

These look like they are new in r12801. I am somewhat fond of reading
lots of wrapper functions, and I have a mild appreciation for API
deprecation, but I don't have too much time to read a longish commit
message, so I don't know if that commit is for me. :-)

Seriously though, am I doing something wrong? (Sorry I'm not able to
investigate the code much further on my own right now.)
