[yt-users] Flashfields error on install

[Cameron Hummels]

  Hey everyone:

     I just pulled the newest version of yt and installed it on kraken.  
It installed OK (installing locally HDF5, zlib, libpng and python).  I 
remembered to swap the PGI modules to the GNU modules.  Unfortunately, 
when I go to run it I get the following error involving "FLASHFields":

$ yt
Traceback (most recent call last):

   File "/nics/b/home/chummels/source/yt/yt/lagos/__init__.py", line 79,

     from FLASHFields import *
ImportError: No module named FLASHFields

I've never seen this error, and I investigated a bit but couldn't find 
much about it.  Any ideas from people?  What is this mysterious 
FLASHFields module?
