Summary: 2.1c1: make setup.py check zlib version

Initial Comment:
Currently, setup.py will build the zlib module without
checking whether the version of zlib on the target
system is up to date (or at least 1.1.3). The module
will thus be built on a stock SGI system where the zlib
version is 1.0.4. WHen the zlib test is run, a core
dump results. The patch below checks the version of
zlib, and only builds if >= 1.1.3
