[buildd-tools-devel] Bug#586275: sbuild: alternative build-deps and Provides do not work correctly

[Ansgar Burchardt]

Package: sbuild
Version: 0.60.0-1
Severity: normal

Hi,

sbuild does not handle alternative dependencies that are also Provided
by another package correctly:

libcpan-meta-perl_2.101670-1 has a build-dependency on
libversion-perl (>= 1:0.8200) | perl (>= 5.12).  libversion-perl is also
provided by perl-modules.

sbuild fails to resolve this dependency:

  libversion-perl: non-matching version installed (~*=PROVIDED=*= ! >= 1:0.8200)
  Using default version 1:0.8200-1
  perl: non-matching version installed (5.10.1-13 ! >= 5.12)
  Default version of perl not sufficient, Package installation not possible
  Source-dependencies not satisfied; skipping libcpan-meta-perl

Somehow it looks like it wants to install both alternatives?

When the alternative on perl (>= 5.12) is removed, sbuild builds the
package just fine.

Regards,
Ansgar
