  Yeah, I must admit I'm a bit puzzled, libxml2 should now respect
zlib interface and the libxml2 patch was actually provided by Mark Adler
himself, so it ought to be correct ! Also libxml2 and the new zlib
have shipped for a while and that's the first time I hear about
such a problem, so something weird is going on, but what ???
  One of the things I'm wondering is the plugin for Firefox isn't
running 32 bits and somehow there is a zlib dependancy problem
there...
