Bug#632693: lintian: False positive with dh_python-is-obsolete

[Daniele Tricoli <eriol@mornie.org>]

Package: lintian
Version: 2.5.1
Severity: normal

Hello,
in the pyke package[¹] I'm using the dh_python-ply helper written
by Jakub Wilk to handle python-ply dependency (see #627862 for
details).

lintian is giving me this:
W: pyke source: dh_python-is-obsolete line 50

Where line 50 of debian/rules is:
    dh_python-ply pyke/krb_compiler/*_tables.py

Many thanks,
