The problem is that, thanks to libtool, if someone has a binary that
they built with

  libtool --mode=link $(CC) -o foo foo.o -lsvn_ra-1

libtool will turn that into

  $(CC) -o foo foo.o -lsvn_ra-1 -lsvn_ra_local-1 -lsvn_ra_svn-1 -lsvn_ra_dav-1 -lapr1 -laprutil1 -lneon ...

Now, if the user upgrades to Subversion 1.5, his binary will break,
because the runtime linker will look for libsvn_ra_dav, even though it
doesn't actually need it.

This isn't a problem in Debian because we use the Debian version of
libtool (the famous Debian's Broken Libtool) which tries to avoid this
recursive linking. But it will happen everywhere else.
