Error with Malthfind Plugin

[jtrombley90]

Adding the Malthfind plugin shows an import error for callstacks.py. Callstacks needs to be in the volatility/plugins/malware directory which i have but is VolUtility aware of that?

Error:
Failed to import volatility.plugins.malthfind (ImportError: No module named callstacks)
~/VolUtility/plugins/malthfind.py(13)()

Thanks,
Josh
