Created attachment 294435 [details] build.log (dev-util/pkgconfig was not installed) ... checking for x86_64-pc-linux-gnu-pkg-config... no checking for pkg-config... no checking for libpipeline... no configure: error: in `/var/tmp/portage/sys-apps/man-db-2.6.0.2/work/man-db-2.6.0.2': configure: error: The pkg-config script could not be found or is too old. Make sure it is in your PATH or set the PKG_CONFIG environment variable to the full path to pkg-config. Alternatively, you may set the environment variables libpipeline_CFLAGS and libpipeline_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details. To get pkg-config, see <http://pkg-config.freedesktop.org/>. See `config.log' for more details ... After installing dev-util/pkgconfig man-db builds fine.
should be all set now in the tree; thanks for the report! Commit message: Pull in pkg-config for building http://sources.gentoo.org/sys-apps/man-db/man-db-2.6.0.2.ebuild?r1=1.9&r2=1.10
