Subversion just has a bunch of unit tests that you can run as part of the
make. I am not sure why they would fail, but there could be a legitimate
reason. You could potentially just ignore them as it is possible the
problems were just in the test environment itself.

On Linux, you are right that Subversion is very tied up with the internals
of your system. This is because it uses so many common components like
APR, BDB and OpenSSL. Worse, it tends to need recent versions of all of
them. Since so much other Linux software uses these same components it
can lead to issues. It is all over my head.

Subclipse is just caught in the middle of all of this. We are just a
normal Eclipse java plugin, but since we have to use JavaHL, which is part
of Subversion, we cannot avoid being dragged into these issues as well.

I would suggest that you try to follow the normal build instructions that
were posted previously.
