Based on your comment above, here are my particulars:

1)  System is LinuxFromScratch recently built from their SVN book:
        glibc is 2.5, gcc is 4.1.2, X is Xorg 7.2 installed in /usr.

2)  Python 2.5.1 with Tkinter enabled.   If I run the following script, 
I get the 'quit' button which when clicked makes the button/window 
disappear, so I know python and Tkinter are working.

#!/usr/bin/python
from Tkinter import *
class Application(Frame):
    def __init__(self, master=None):
        Frame.__init__(self, master)
        self.grid()
        self.createWidgets()
    def createWidgets(self):
        self.quitButton = Button ( self, text="Quit",command=self.quit )
        self.quitButton.grid()
app = Application()
app.master.title("Sample application")
app.mainloop()

3)  Numpy 1.0.3.1 installed without any errors and I can do the following:

 >>> import numpy
 >>> List = dir(numpy)
 >>> len(List)
491
 >>>

4)  Matplotlib 0.90.1 also installed without error.  I set 
BUILD_TKAGG       = 1 which may not have been necessary, but it seems to 
have worked since in my matplotlibrc file I find "backend      : 
TkAgg".  Then if I do this
" python simple_plot.py --verbose-debug",  I get the output in the 
simple_output attachment.  The font errors there are the same as what I 
get in each of my 3 XP installations where matplotlib works just fine, 
so I don't think they are the cause of the segfault.  As I may have 
described previously, the plot window appears for a fraction of a second 
and then disappears as the segfault occurs.

I also ran "strace python simple_plot.py --verbose-debug" with the 
output that's in the strace_output attachment to see if that would give 
any more information but that output ends at the segfault and I am not 
knowledgeable enough to understand what it says.

Any help will be appreciated.

Best Regards,

Wayne
