libz.so not found under Mac OS X

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Compilation of a simple HelloWorld code with gpuocelot under Mac OS X
2. Execution

What is the expected output? What do you see instead?
Exception thrown, because the dynamic library libz.so cannot be found. Under 
Mac OS X it is called libz.dylib.


What version of the product are you using? On what operating system?
gpuocelot 2.0.969 with hydrazine included. 
Compiled with gcc (MacPorts gcc46 4.6.3_9) 4.6.3 under Mac OS X 10.8.2.
Installed through gpuocelot.

Please provide any additional information below.
A possible solution is to open the libz.dylib file instead of the libz.so file 
(hydrazine/implementation/compression.cpp).

33: void* libz = dlopen("libz.so", RTLD_LAZY); 

A check for both library names solves the issue.
