Re: [Matplotlib-users] Install problems, OSX 10.6.8, Python 3.3.1

[Michael D. <md...@st...>]

Do any Mac experts have any ideas?

One thing that may help us is to fire this up in gdb and get a traceback.

1) Run "gdb python" (or "gdb python3").
2) At the gdb prompt, type "run"
3) At the Python prompt, type "import matplotlib.pyplot"
4) Python should crash, then type "bt" to get a backtrace
5) Post the *complete* backtrace to this list and maybe it will make the 
problem more obvious to us
