It seems that the package has been built in an environment lacking /dev/shm, and therefore the test program failed, hence the value of Netsys.have_posix_shm.
AFAICT, this is an issue in Ubuntu building infrastructure, not in the package itself. I could make the package building fail if /dev/shm is not mounted... but it would then always fail in Ubuntu build farms... is that what we want?
