Ethereal gets the version number directly from the zlib.h header file,
via the ZLIB_VERSION macro. If Ethereal eports verson 1.0.8, then
somewhere a macro called ZLIB_VERSION is being defined as "1.0.8".
It's highly likely that you are picking up an incorrect zlib version.

Other possiblities are that you are using a correct zlib version, but
for some reason it has the wrong zlib.h file, or that some other
non-zlib-related file is defining ZLIB_VERSION.
