Bug#694530: dh-make-perl: Unprotected used of $tarball

[Cyril Brulebois]

Package: dh-make-perl
Version: 0.76-1
Severity: normal

Hello,

I've just tried to use dh-make-perl in a directory extracted from
a CPAN module tarball, and got the following. See the lines below
the arrow for the actual issue:
