So it sounds like if we were to make the build system effectively
require (or even automatically perform) a "make uninstall" before
"make", that would solve it. That's not a good solution in general
because it's useful to be able to build before losing the current
install, on systems where that works, but it sounds like it would fix
the problem on systems like mine. Even a pre-make check that reported
"WARNING: You have Subversion libraries already installed in the
installation directory. This is known to cause incorrect linking on some
systems." would help.
