[mosaic] error running mosaicGUI.py on Ubuntu 14.04

[Kyle Briggs]

When trying to run "python mosaicgui/mosaicGUI.py" I get the following
error when running from source:

Traceback (most recent call last):

And I get the following error when trying to run it from the installation:

It is unable to find one of the UI files.

It is possible the installed version is taking precedence over the source. You could delete the installed version by running:

rm -r `python -c "from distutils.sysconfig import get_python_lib; print(get_python_lib())?`/mosaic*

Then change into the source directory and run:

export PYTHONPATH=$PWD

To make the PYTHONPATH change permanent:

echo "export PYTHONPATH=$PWD? >> ~/.bashrc
