> The native zlib code currently uses dlopen/dlsym to dynamically load libz. This used
to make sense when there was an lzo option (so you could load libhadoop for lzo purposes without
requiring libz as well). Now that libhadoop only has zlib as an option, it makes sense to
just add it as an ld flag and let it be automatically loaded as a shlib dependency. I also
doubt that there are any distros where libz isn't required by the base system.
