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