[Debian-med-packaging] Bug#996541: racon: FTBFS when rebuilt against libedlib1

[Niels Thykier]

Package: racon
Version: 1.4.21-1
Severity: serious
X-Debbugs-Cc: niels at thykier.net

Hi,

A new version of libedlib (with a new ABI) has been uploaded to
unstable and that causes racon to fail to build from source.

Relevant parts of the amd64 log:
