Idea 0 (which will probably happen anyway): change the debhelper
version back to x.y*

Idea 1: remove this whole check; debhelper >= 9.20120909 is already
satisfied in oldstable, so this doesn't serve any purpose any more.

Idea 2: For a real check, I'd probably try to start with checking out
Dpkg::Version in libdpkg-perl.

And since I was curious, I tried it out and it seems to work:

% perl -MDpkg::Version -E '$given=10; $required=Dpkg::Version->new("9.20120909"); say "satisfied" if $given >= $required;'


% perl -MDpkg::Version -E '$given=10; $required="9.20120909"; say "satisfied" if version_compare($given, $required)>=0;'


% perl -MDpkg::Version -E '$given=10; $required="9.20120909"; say "satisfied" if version_compare_relation($given, REL_GE, $required);'
