Well, the problem, IIRC, was some leftover makefile.  So it's rather a
problem of `svn update' not being able to delete files that were not
part of svn (like all of the `Makefile's.)

Running `make clean' before an svn update is better, but still it's
not enough -- for example, I don't think that `make clean' removes
makefiles, and that was the problem in your case.

It's really best to do what I did -- it works just as fine after an
`svn up', but when there are changes with files being removed you have
the option of blowing up the whole build directory and starting again.
