Looks like a missing library reference.

Shared object ("*.so") linking is sensitive to missing libraries.
Because many symbols cannot (yet) be resolved (e.g. all
symbols from Python), the linker cannot detect a missing
library reference. A missing reference leads to "undefined symbol"
error when the shared object is loaded.

The missing compress is probably defined in "libz".
Thus, you link command almost surely lacks an "-lz"
library reference.
