I had a similar problem building Subversion on Ubuntu. I couldn't
build trunk Subversion because libtool linked to the wrong libs.
Installing a vanilla version of libtool fixed the problem. But that's
just me -- every system is different. Did you remember to re-run
autogen.sh && ./configure ?

I don't completely understand what you're doing, but it looks like
you're reordering the dependencies so that the build system will build
them in the correct order. If you have to do this, it's likely because
we've forgotten to list some essential dependencies somewhere else in
the build system.

In your case, it looks like patching libsvn_ra to depend on
libsvn_delta will fix your problem. I figured this out by looking at
libsvn_ra-1.la, and noticing that it contains a reference to
libsvn_delta, but then also noticing that libsvn_ra does not depend on
libsvn_delta in build.conf.

The same rule applies here. You can use the same detective techniques
to find out the true dependencies of each module. In general, if you
find that listing module "y" after module "x" works, but listing it
the other way does not, you can bet that y depends on x.

Hope this helps,

David
