Bug#805968: libmath-derivative-perl: FTBFS with perl 5.22: missing dependency on Module::Build

[Dominic Hargreaves]

Source: libmath-derivative-perl
Version: 0.04-1
Severity: serious
Justification: will FTBFS with upcoming transition
User: debian-perl at lists.debian.org
Usertags: perl-5.22-transition
Tags: sid stretch

This package FTBFS with perl 5.22, which is in experimental and due
to transition to unstable soon:

        perl Build.PL --installdirs vendor
Can't locate Module/Build.pm in @INC (you may need to install the Module::Build module) (@INC contains: /etc/perl /usr/local/lib/x86_64-linux-gnu/perl/5.22.0 /usr/local/share/perl/5.22.0 /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 Build.PL line 4.
BEGIN failed--compilation aborted at Build.PL line 4.
dh_auto_configure: perl Build.PL --installdirs vendor returned exit code 2
debian/rules:4: recipe for target 'build' failed
make: *** [build] Error 2
dpkg-buildpackage: error: debian/rules build gave error exit status 2

The problem is solved by build-depending on libmodule-build-perl
(which used to be bundled with perl until 5.22).

Cheers,
Dominic.
