/usr/lib64/pkgconfig/OpenIPMIpthread.pc: (...) Requires: OpenIPMI pthread (...) but there is no pthread.pc (should be installed by libc I guess) Same issue on SuSE11, with (it seems) a simple patch: https://bugzilla.novell.com/show_bug.cgi?id=388026
Fixed in sys-libs/openipmi-2.0.16-r1 (Version bump since collectd depends on the proper file)
