The main trouble with all of this is that LD_LIBRARY_PATH is irrelevant
here.
From man ld.so.1:
SECURITY To prevent malicious dependency substitution or symbol interposition, some restrictions may apply
tothe evaluation of the dependencies of secure processes.
The runtime linker categorizes a process as secure if the user is not a super user, and either the real
userand effective user identifiers are not equal, or the real group and effective group identifiers are
not equal. See getuid(2), geteuid(2), getgid(2), and getegid(2).
If an LD_LIBRARY_PATH environment variable is in effect for a secure process, then only the trusted
directoriesspeci- fied by this variable will be used to augment the runtime linker's search rules.
Presently,the only trusted direc- tory known to the runtime linker is /usr/lib.
There are many way to solve the problem:the easy -- copy (or link) libz.so to /usr/libthe clean -- avoid using
LD_LIBRARY_PATH,use -R for linking instead
