Package: libqoauth-dev Version: 2.0.1~1-3+b1 libqoauth-dev installs both /usr/lib/pkgconfig/qoauth.pc and /usr/share/pkgconfig/qoauth.pc. Usually, every pkgconf package name should be provided by only one location. It doesn't seem to be really bad here, because their contents equal and therefore it does not practically matter which one is chosen, but this still is an odd practice and is better discontinued. libqoauth-dev is the only package in Debian that installs a .pc file twice.
Also note that installing it to /usr/lib/<triplet>/pkgconfig would be even better, because otherwise pkgconfig --exists qoauth could erroneously return success when in fact libqoauth-dev is not installed for the architecture in question. Helmut
