[svn-r2630] Purpose:
	Bug Fix
Description:
	zlib was not being retrieved from the place specified by the user
	even if the user used the --with-zlib flag.
Solution:
	Removed the automatic inclusion of /usr/ncsa/* into the macros
	and use the user-defined place to try to pickup the zlib. I'm
	relying on the order of the -L flags in the compile line to
	specify which libraries to look into first before going on to
	look into the system libraries. If some compiler doesn't honor
	the this order, yikes...
Platforms tested:
	Linux
