Bug#850000: libdebian-source-perl: fails to parse build-depends restriction formulas

[David Bremner]

Package: libdebian-source-perl
Version: 0.92
Severity: normal

Debian::Dependency is used by dh_elpa_test (source dh-elpa) to parse build deps, but it chokes on
build profiles, so called "restriction formulas".

for example

Build-Depends: debhelper (>= 10),
 dh-elpa,
 racket <!nocheck>

% dh_elpa_test

leads to

Unable to parse 'racket <!nocheck>' at /usr/share/perl5/Debian/Dependency.pm line 331
