AIUI, it looks like the code you try to compile uses the deflate() function from libz, and doesn't link it directly (i.e. the "-lz" compiler option) but indirectly (i.e. links a library which uses libz). You need to explicitly link all libraries that you use, you may not depend on other libraries pulling these in.
