The issue is "use base" of a module without using it first: Base class package "t::FileStub" is empty. (Perhaps you need to 'use' the module which defines that package first, or make that module available in @INC (@INC contains: /«PKGBUILDDIR»/blib/lib /«PKGBUILDDIR»/blib/arch lib /etc/perl /usr/local/lib/x86_64-linux-gnu/perl/5.22.2 /usr/local/share/perl/5.22.2 /usr/lib/x86_64-linux-gnu/perl5/5.22 /usr/share/perl5 /usr/lib/x86_64-linux-gnu/perl/5.22 /usr/share/perl/5.22 /usr/local/lib/site_perl /usr/lib/x86_64-linux-gnu/perl-base .). at t/FileStubChunked.pm line 11. And the fix is easy: $ diff -u t/FileStubChunked.pm{.orig,} --- t/FileStubChunked.pm.orig 2011-05-06 12:24:03.000000000 +0200 +++ t/FileStubChunked.pm 2016-08-07 13:17:36.272822915 +0200 @@ -8,6 +8,7 @@ package t::FileStubChunked; use strict; use warnings; +use t::FileStub; use base qw(t::FileStub); our $VERSION = do { my @r = (q$Revision: 19 $ =~ /\d+/mxg); sprintf '%d.'.'%03d' x $#r, @r }; Cheers!
