I think this is because you configured subversion using --enable-dso.

You can verify that the build is using libraries from within the build
tree by running:

$ ldd subversion/clients/cmdline/.libs/lt-svn | grep libsvn

This should show the libraries being picked up from the build area.

I think official libtool way to run the command would be:
$ ./libtool --mode=execute ldd subversion/clients/cmdline/svn
but using .libs/lt-svn directly works for me.

Since you used --enable-dso additional libraries get loaded at
runtime, to see what gets loaded use:

$ strace -etrace=open subversion/clients/cmdline/.libs/lt-svn 2>&1 | grep libsvn_ra-1

I expect this will show libraries being loaded from outside the build
area. The exact set of paths searched for --enable-dso libraries
depends on how your system is configured. It may be possible to use
LD_LIBRARY_PATH to change this, try adding:

/path/to/build/dir/subversion/libsvn_ra_local/.libs

to LD_LIBRARY_PATH and repeat the strace command to see if it works.
You will probably need to add libsvn_fs_fs as well, and possibly
libsvn_ra_dav, libsvn_ra_svn and libsvn_fs_base, to get the regression
tests to pass.

Using LD_LIBRARY_PATH didn't work on --enable-dso libraries the last
time I tried it on my machine, which means there is no way to make
--enable-dso regression tests work without first installing
Subversion.
