I can reproduce this error with 2.1.1 built from source on Ubuntu 14.04 and 
Python 3.4. Unfortunately, I think MixMaster has not been maintained for some 
time, and I am unsure when this might be fixed (although another developer may 
have a different perspective). You will probably get this fixed the fastest by 
Googling the error message and trying to fix it yourself. Otherwise, using the 
GUI is not really necessary and you can use the interface from a Python or 
iPython prompt quite easily.

Okay, short debugging show that simple replacing line 107 in file 
mixmaster/ControlPanel.py from
    button.pack(side=LEFT)
to
    button.grid()
solves the problem.
Can anybody check (and probably commit) this?

Looks like the correction I have proposed is not perfect.
Top menu now is displayed vertical, not horizontal.
However mixmaster is functional.

This bug is apparently due to a change in behavior in Tcl 8.6.0 which is the 
version available in Ubuntu 14.04 (13.10 used Tcl 8.5).

This post has some information (it's an intentional change in behavior, and 
there's no generic fix):
