Yes. You've already found it.

Are you SURE you want msys-z.dll? This is a zlib library that requires 
the GPL'ed msys-1.0.dll to operate. Which means that any client code 
that uses msys-z.dll must be released under the GPL.

(and, zlib-1.2.3-MSYS-1.0.11-1.tar.bz2 already provides msys-z.dll).

Most people shouldn't concern themselves with MSYS components; they 
should be regarded as TOOLS useful for building *mingw* (that is, native 
win32) items. Unless you want to help create those tools.


I think it is more likely that you really want a native version of zlib 
(e.g. libz.dll) as the other correspondent suggested. Google 'zlib 
mingwPORT'.

That having been said, to compile MSYS components, you need several 
things. First, you have to install the files in the

MSYS System Builder
   Technology Preview: msysDVLPR-1.0.0-alpha-1 release
category, including:

    msysDVLPR-1.0.0-alpha-1.tar.gz

and updating with
    autoconf-2.61-MSYS-1.0.11-1.tar.bz2
    automake-1.10-MSYS-1.0.11-1.tar.bz2
    libtool1.5-1.5.25a-20070701-MSYS-1.0.11-1.tar.bz2
    termcap-20050421-MSYS-1.0.11-1.tar.bz2

Secondly, you have to launch msys.bat with the argument "MSYS". This 
will set the appropriate environment variables and set your PATH so that 
the msysDVLPR gcc (a variant of gcc-2.95.3) appears in your PATH before 
the mingw gcc-3.4.5.

THEN the msys-build-zlib script inside 
zlib-1.2.3-MSYS-1.0.11-1-src.tar.bz2 will work for you.
