'python-matplotlib' does not install depencency 'python-tk'

[Bwoaas]

Binary package hint: python-matplotlib

Using Ubuntu 8.10
Matplotlib: 0.98.3-4ubuntu1
Python: Python 2.5.2 (r252:60911, Oct 5 2008, 19:24:49)

After installing 'python-matplotlib', using matplotlib failes with an error [1]. After installing 'python-tk' this problem is solved. I think 'python-tk' should be a dependency of 'python-matplotlib'.

[1]:
Matplotlib
