It isn't installed, as far as I can see. I expected it's in some 
optional package that is absent on that build platform.

Although cfarm119 does have a file /opt/freeware/include/zlib.h, that 
corresponds to /opt/freeware/lib/libz.a, not to what -lz picks up which 
is /usr/lib/libz.a (a symlink to /usr/opt/rpm/lib/libz.a). I wouldn't 
recommend mixing up versions like that.

Not sure that would be a good idea as this isn't an AIX-specific 
problem. Anybody can mess up .h and -l in this way, on any OS.

On the same platform I discovered a similar problem with -lsqlite3. I 
fixed both problems on master by installing the attached, and I'm 
marking the bug as done.

For the release branch I suppose we can just say something like "just 
use --without-zlib if you have problems".

As I'm sure you know, this library configury is waaay too complex and 
idiosyncratic. Why don't libz and libsqlite3 use pkg-config, for 
example? But I'm inclined to let the relevant library experts deal with 
that whenever they have time.
