My take on this is that Linux doesn't do any pre-binding at compile time,
but everything is resolved at run-time.
You can ignore the fact that gcc is using your libz from /usr.
The problem is the runtime.
Did you try to give to LD_LIBRARY_PATH an absolute path instead of a
relative path?
What does 'ldd' shows after that?
What happen if you 'hide' (temporarily) your /usr/libz.so? Does ldd see your
local one?
Try to change the search order from /etc/ld.so.conf and re-run ldconfig.
