So I followed those instructions to compile PySide myself. All seemed to 
go through fine and installed it here:


I can import PySide ok, but when I now try to import PySide.QtGui I get 
this error:

from PySide.QtGui import *
Traceback (most recent call last):
   File "/ohufx/pipeline/tools/python/PublishPanel/PublishPanel.py", 
line 2, in
ImportError: libpyside-python2.7.so.1.2: cannot open shared object file: 
No such file or directory

Is that what your problem was?
I didn't catch any errors when it was compiling. Is there a log that I 
can check after the fact?
