Thanks for the explanations.

I'm not convinced that specifying an abspath is the end of the world; we
already do that for the "normal" shared libraries. (They get relinked
during 'make install', and if I rename the dir they were installed to
I get an error.)
% mv prefix suffix
% suffix/svn-1.7.0/bin/svn
suffix/svn-1.7.0/bin/svn: error while loading shared libraries: libsvn_client-1.so.0: cannot open shared object file: No such file or directory
On the other hand, I'm more concerned about how an installed libsvn_subr
loads its libsvn_auth_* libraries than about how auth-test does that.
I suppose the problem here would be that if one, for whatever reason,
has two copies of libsvn_auth_kwallet in $LD_LIBRARY_PATH:$LD_DEFAULT_SEARCH_PATH,
then svn will load the wrong one.
Which can probably lead to nastiness in one circumstances or another...
Thanks,
Daniel
