           Summary: zlib version check is fake in the configure script.
                    installation failure.
           Product: Portable OpenSSH
           Version: 5.1p1
          Platform: ix86
        OS/Version: Linux
            Status: NEW
          Severity: major
          Priority: P2
         Component: Build system
        AssignedTo: unassigned-bugs at mindrot.org
        ReportedBy: re.bmgr at gmail.com


It seems like whatever the version of zlib is, the message "zlib too
old" which
precedes the installation failure always appears if the option
--without-zlib-version-check
 is not used while calling the configure script. 

Reminder : Openssh needs at least zlib version 1.2.3.

If someone checks the configure script then check the line 10672 :
one can see that the script checks if the variable $zlib_check_nonfatal
is set
:
[line10672] if test -z "$zlib_check_nonfatal" ; then
    - If the variable $zlib_check_nonfatal is set then "zlib too old"
does not
happen.

The big problem is that the only other place where $zlib_check_nonfatal
could
be set
is at line 10598 :
[line 10598] zlib_check_nonfatal=1

which ONLY happens if --without-zlib-version-check is used.


May be my mistake... so if someone could check that and have a correct
zlib
version check
that would be nice.

Best regards.
