This could cause problems for packagers. 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 (the question is which, and how likely it is)
