sys-libs/glibc-2.15-r2.ebuild and older include the following: NPTL_KERN_VER=${NPTL_KERN_VER:-"2.6.9"} # min kernel version nptl requires [...] [[ ${CTARGET} == hppa* ]] && NPTL_KERN_VER=${NPTL_KERN_VER/2.6.9/2.6.20} Which changes NPTL_KERN_VER from 2.6.9 to 2.6.20 for hppa. >=sys-libs/glibc-2.16.0 currently include: NPTL_KERN_VER=${NPTL_KERN_VER:-"2.6.16"} # min kernel version nptl requires [...] [[ ${CTARGET} == hppa* ]] && NPTL_KERN_VER=${NPTL_KERN_VER/2.6.9/2.6.20} Which fails to change the version from 2.6.16 to 2.6.20. I noticed this by grepping through the ebuild. As I don't use hppa, I have no build.log, and my emerge --info is quite useless. Thanks for your work!
should be all set now in the tree; thanks for the report! Commit message: Fix default hppa nptl kernel version http://sources.gentoo.org/sys-libs/glibc/glibc-2.16.0.ebuild?r1=1.1&r2=1.2 http://sources.gentoo.org/sys-libs/glibc/glibc-9999.ebuild?r1=1.11&r2=1.12
