It's both. I said this in response to people telling me "you should
upgrade your svn client as well", and since I didn't know that was
necessary, I didn't do that because of it needing manual tweaking to
get to build. I later found out that at the point where the build
failed (in libsvn_client-1.a, with a bunch of undefined references),
the svn commandline client had already been built. For some reason,
this is now a 6.4M binary (!) so I definitely will need to look at
what's getting included there. Anyhow, I got a svn which worked, apart
from the crash I mentioned.

No; it calls auth_file_path() which calls svn_path_join(). Sorry for

This is indeed what happens. I put in some more debugging printf()s
and indeed the svn_config__user_config_path() in
config_auth.c::auth_file_path() makes authdir_path NULL. I will look
at the BeOS APR port - it's probably the cause of the problems.
Thanks for the suggestions. I'll get back with the results from my APR
