[CIG-SHORT] Traceback Error

[BOK10 at pitt.edu]

I've been trying to run my model, but recently I've been getting this
error. Is there any insight as to what the problem might be?

Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: No module named merlin
/usr/local/pylith/bin/pylith: /usr/local/pylith/bin/nemesis: exit 1
