Problem with install python matplotlib - segmentation fault

[Everett, Thomas]

All I really need is some form of graphical plot options. I googled options and found many that did not work and finally used the setup-x86_64.exe to install matplotlib. I thin downloaded some simple examples and I either get nothing, or I get a segmentation fault.

te1025@LP-DLBK1J3 ~/scripts
$ ./simpleplot.py
Segmentation fault

te1025@LP-DLBK1J3 ~/scripts
$ ./linestyles.py
Traceback (most recent call last):

$ ./multicolored_line.py
Segmentation fault

Can anyone suggestion options to get this resolved?

Thanks,
