Package: glibc Version: 2.5-0exp1 Tags: experimental Severity: serious see #374535, it's the GNU_TYPE, not the Debian architecture. $ find /usr/include/ -name stubs*/usr/include/gnu/stubs.h /usr/include/gnu/stubs-32.h /usr/include/ppc64-linux-gnu/gnu/stubs.h /usr/include/ppc64-linux-gnu/gnu/stubs-64.h the headers on powerpc/powerpc64 are identical, so you may install them directly in /usr/include/ as well.
