installing Pithos (Pandora radio client) from source

[euphonious]

I am running ROSA Desktop Fresh R6 on my desktop machine. I desired to use Pithos, a Pandora radio client, which is unfortunately not in the repositories. I attempted to install the program from source as outlined on the page linked below.

https://github.com/pithos/pithos/wiki/I ... rom-Source

I did not see any errors when compiling from source and I think that I have all the dependencies needed but when I run "pithos" to start the program, I receive the output below.

mark@mark-OptiPlex-7010 ~/pithos (master) $ pithos
Traceback (most recent call last):

Can anyone offer me advice on how to correct these errors? Thank you!
