Package: dpkg-dev
Version: 1.19.2
Severity: normal
Control: affects -1 libdnssec6
libdnssec.so.6.0.0 links against pthread, and uses pthread_once.
but dpkg-shlibdeps complains that it is found in none of the
libraries.
I think this is a bug in dpkg-shlibdeps. If not, please let me know
what needs to be done to fix libdnssec.so.6.0.0 (feel free to reassign
the bug in that case.
Here's a shell transcript which describes the problem:
