I gather you build 1.9.5.

This implies that configure doesn't find zlib in the default paths.
That's odd, given that later you indicate that libz was found in
/lib64, which probably _is_ one of the default paths.

Are there any clues in configure's output from this run?

Possibly apr or serf bring in another copy of zlib than the one you intended.
What's the output of Ā«grep "^SVN_.*LIBS =" MakefileĀ»?

Can you show the linker invocation of libsvn_client?
