Bug#583351: libtime-y2038-perl: FTBFS

[Sebastian Andrzej Siewior]

Package: libtime-y2038-perl
Version: 20100403-1
Tags: sid
User: debian-powerpcspe at breakpoint.cc
Usertags: powerpcspe
Severity: serious

None of the buildds [0] built this packges. Well mipsel did but it was
using aptitude to resolve the build-deps while others use sbuild and
this leads to:
| perl: already installed (5.10.1-12 >= 5.6.100 is satisfied)
| libtest-warn-perl: missing
| Using default version 0.21-1
| libtest-exception-perl: missing
| Using default version 0.29-1
| libjson-perl: missing
| Using default version 2.21-1
| perl: non-matching version installed (5.10.1-12 ! >= 5.12)
| Default version of perl not sufficient, no suitable alternative found. I probably should dep-wait this one.
| Package installation not possible
| Source-dependencies not satisfied; skipping libtime-y2038-perl
| Purging /var/lib/schroot/mount/spestage-6d1e5f5e-9e09-43bb-b4cc-ab84f422eeef/spestage/build/buildd-libtime-y2038-perl_20100403-1-powerpcspe-amlOOM
| Not removing build depends: cloned chroot in use

So we have perl 5.10. The dep-line:

  perl (>= 5.12) | libmodule-build-perl (>= 0.36)

Fails because we have perl 5.10 allready _and_ sbuild does not look
for alternatives. So it wants to upgrade perl but it is not possible
because it is only in exp. If perl would not be available at _all_ then
ir would look for alternatives.

Is it possible to fix this somehow?
