Tcl-Tk and Yosemite on Macos

Hi, I just upgraded to Yosemite with latest obspy dev version installed using homebrew.

With this simple code

seedlink-plotter --seedlink_server "rtserver.ipgp.fr:18000"  -s "G_RER:BHZ" -b 3600

I have the following error:

objc[87267]: Class TKApplication is implemented in both /usr/local/opt/tcl-tk/lib/libtk8.6.dylib and /System/Library/Frameworks/Tk.framework/Versions/8.5/Tk. One of the two will be used. Which one is undefined.

_tkinter.TclError

I am sure it is not linked with seedlink-plotter, but I would like to know what is the best way to solve this conflicting library problem. With the following code I have the same error

import Tkinter
from PIL import ImageTk
Tkinter.Tk()
ImageTk.PhotoImage(file='test_image.jpg')
