ImportError: No module named gradunwarp.core

[gbook]

I've setup an HCP environment which includes the gradunwarp module. However, I'm running into an error when executing the HCP. I followed the installation instructions and created a local version of the build. I then copied the build directories to a shared server so they can be accessed by a set of cluster nodes. When I run it through the cluster, I get the error:

Traceback (most recent call last):
File "/opt/HCP/gradunwarp/bin/gradient_unwarp.py", line 11, in
