hi matplotlib developers and users,
let me inform you about the bug:
when I use
sudo aptitude install python-matplotlib
it downloads LOTS of auxilary packages (IIRC about 200 MB for download and 400 MB for HDD after unpack, or kind of), still it doesn't work after installation, it yields
ImportError: No module named _tkinter, please install the python-tk package
when I install python-tk (1.7 MB for download, very small size in comparison with those 400 MB), all works OK.
I hope you will have it fixed.
