Description of problem:
The given source URL ftp://ftp.info-zip.org/pub/infozip/zlib/zlib-%
{version}.tar.gz has been invalid for quite some time.

Version-Release number of selected component (if applicable):
1.2.1.2-1

How reproducible:
always

Steps to Reproduce:
1. read "Source:" tag in zlib.spec file
2. go to ftp://ftp.info-zip.org/pub/infozip/zlib/
  
Actual results:
No current source available.

Expected results:
Find source.

Additional info:
I was trying to find the original location of zlib-1.2.1.x. In the 
official location (which is now actually http://www.gzip.org/zlib/
zlib-%{version}.tar.bz2), the newer sources 1.2.1.1 and 1.2.1.2 are 
not available. Where the he** did you ever get them from??? Debian's 
system also won't show me their original source location.
