Bug#548367: dh-make-perl: Detecting alternative dependencies

[Slaven Rezic]

Package: dh-make-perl
Version: 0.47
Severity: wishlist

It seems to me that dh-make-perl could detect alternative dependencies in
a better way. Currently it seems that it picks one by random. For example

$ dh-make-perl --build --cpan GD::SVG; dpkg --info
libgd-svg-perl_0.33-1_all.deb
...
Needs the following debian packages: libgd-gd2-noxpm-perl, libsvg-perl
...
 Depends: perl (>= 5.6.0-16), libgd-gd2-noxpm-perl, libsvg-perl

But libgd-gd2-noxpm-perl is not the only candidate satisfying the GD.pm
requirement:

$ apt-file search perl5/GD.pm
libgd-gd2-noxpm-perl: /usr/lib/perl5/GD.pm
libgd-gd2-perl: /usr/lib/perl5/GD.pm

So it would be nice if this could be automatically turned into something
like

    libgd-gd2-perl | libgd-gd2-noxpm-perl

Regards,
    Slaven
