Your problem is one that plagues Linux. You compile and link against
one version of a library, and then you runtime link against another
version. This should have been fixed for users a long time ago, but
the folks responsible leave users to suffer it. I consider it a
security bug since essentially random libraries are being loaded at
runtime.
To fix the problem yourself, add an RPATH to your LDFLAGS when
building your program:
-Wl,-rpath=/path/to/expected/libz -Wl,--enable-new-dtags
The loader will encounter the RPATH when loading your executable, and
load the correct library for your program.
