[Pkg-kde-extras] Bug#963857: gammaray: FTBFS on IPv6-only environments

[Dominic Hargreaves]

Source: gammaray
Version: 2.11.1-1
Severity: serious
Justification: FTBFS (when it built before)

During archive-wide test rebuilding of an IPv6-only environment (which
appears on some normal buildds)[1] we noticed that this package fails:

: No symbol table info available.

The full log is available at http://perl.debian.net/rebuild-logs/sid-v6only/gammaray_2.11.1-1/gammaray_2.11.1-1_amd64-2020-06-14T14:09:54Z.build

One way to replicate this environment is like so:

  # unshare -n
  # ip li set lo up
  # ip li add dummy0 type dummy
  # ip li set dummy0 up

[1] this test showed approximately 100 packages in the archive failing,
but nearly all of them were due to the behaviour of libio-socket-ip-perl,
so will be fixed centrally. I'm filing bugs about the small number of
unrelated cases.
