Ah probably so..
I was dumbly doing a
setup scipy
at the command line, since some of our scripts use it

Ok.. so here's the real issue I think..  when I go to run one of our
scripts that uses scipy, I receive an error:

RuntimeError: module compiled against API version 7 but this version of
numpy is 6

Anaconda came along with numpy 1.7.1, but the DMstack is expecting
1.6.2+1..and I suspect downloaded it and used it rather than the
Anaconda version.  Does that seem possible?
Similiarly I see matplotlib 1.1.1+2 installed under DM while Anaconda
has 1.3.1.  Definitely need the Anaconda version of numpy to be used,
while maybe it doesn't matter for matplotlib.

If I fire up python, I see:
Python 2.7.5 |Anaconda 1.8.0 (64-bit)| (default, Nov  4 2013, 15:30:26)
[GCC 4.1.2 20080704 (Red Hat 4.1.2-54)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import numpy
>>> print numpy.__version__
1.6.2

so somehow my environment picks that older version of numpy up rather
than the Anaconda version.  Help!  :)

Take care,
Heather
