  Mark,

   You can try what the configure error message should be suggesting (it is not clear if that is being printed to your screen or no).

ERROR: Unable to download package ZLIB from: http://www.zlib.net/zlib-1.2.11.tar.gz

My browser can not open this and I could not see a download button on this site.

Can you download this?
 

* If URL specified manually - perhaps there is a typo?
* If your network is disconnected - please reconnect and rerun ./configure
* Or perhaps you have a firewall blocking the download
* You can run with --with-packages-download-dir=/adirectory and ./configure will instruct you what packages to download manually
* or you can download the above URL manually, to /yourselectedlocation/zlib-1.2.11.tar.gz
  and use the configure option:
  --download-zlib=/yourselectedlocation/zlib-1.2.11.tar.gz
