Source: python-cobra
Version: 0.4.1-2
Severity: important

Hi,

python-cobra FTBFS on hurd-i386, but the previous version built there:

https://buildd.debian.org/status/fetch.php?pkg=python-cobra&arch=hurd-i386&ver=0.4.1-2&stamp=1464980277

ImportError: This platform lacks a functioning sem_open implementation, therefore, the required synchronization primitives needed will not function, see issue 3770.

If this is not trivially fixable, please request decrufting of the
outdated binary packages:

Control: reassign -1 ftp.debian.org
Control: severity -1 normal
Control: retitle -1 RM: python-cobra [hurd-i386] -- RoM; FTBFS; platform lacks a functioning sem_open implementation
