While trying to use signal.freqs, I get the following error:
<error>
In [1]: from scipy import *
In [2]: [w, h] = signal.freqs([1, 2, 5626], [1, 2, 2])

26
27 integ = abs(ez) < 1e-10
NameError: global name 'r_' is not defined
</error>
However, r_ seems to work when I try it from the ipython console.
This has been fixed in the svn repository. Could you please include it
in the Debian packaged version?

Thanks.
