You still have a grep there. What's the output of the strings command 
(no pipe at all)?

Interesting. You have the same version of libzip.so that I do. Perhaps 
Sun forgot to mangle it on the AMD 64 platform? Anyway, there are ways 
around it. To my knowledge, the only PostgreSQL utilities that make use 
of the zlib are the dump/restore so one way to go around this is to 
recompile the backend configured with --without-zlib. Meanwhile, I'll 
see if I can get access to an AMD 64 machine...
