[CIG-SHORT] PyLith install problem?

[William Brower Levandowski]

Hello--
I am working through setting up and testing PyLith for the first time on
OSX 10.8.
In attempting to verify proper installation, I tried the tutorial
axialdisp. (i.e., *pylith axialdisp.cfg* in directory
~/src/pylith/pylith-1.9.0/examples/twocells/twotri3)
The initialization and mesh building seem fine, but then the following
abnormal ending message occurs:

*Fatal error. Calling MPI_Abort() to abort PyLith application.*
*Traceback (most recent call last):*

No vtk files are produced.

Does anyone see an obvious goof on my part, or did I mess something up in
the install? (I notice that the directory structure is slightly different
from that described in the tutorial. I configured using the desktop-darwin
instructions and already had Python 3.4 installed, if that matters.)
If the latter, removing and reinstalling PyLith should be straightforward.

Thanks so much for your help,
Will
