Its' RPM is identified as follows:

rpm -qf /usr/lib64/libz.so.1.2.1.2
zlib-1.2.1.2-1.2

> VTK's is 1.1.4, which is quite old.
Isn't that a security hole of some kind? I though many updates to zlib
since then were security patches? I don't remember any interface changes
, at least my own software that uses zlib has just kept working through
these updates, why is this old version desireable and why should it need
differently named functions ?

Just wondering ...
