The ebuild contains this to extract the requested job number from $MAKEOPTS which is a Good Thing. Unfortunately the construct fails when MAKEOPTS contains -j resp. --jobs without argument (unlimited/limited by accompanying --load-average=NN): NUMJOBS=$(sed -r -e 's/--jobs=?/-j/; s/.*(-j ?[0-9]+).*/\1/' <<< ${MAKEOPTS}) Reproducible: Always Steps to Reproduce: 1. configure MAKEOPTS to sth. like "--jobs --load-average=3.0" 2. try to build boost Actual Results: As the second substition in the line quoted above fails, this leads to an invokation like: bjam-1_41 -j --load-average=3.0 -q gentoorelease -sICU_PATH=/usr --without-mpi --user-config="/var/tmp/portage/dev-libs/boost-1.41.0/work/boost_1_41_0/user-config.jam" --boost-build=/usr/share/boost-build-1_41 --prefix="/var/tmp/portage/dev-libs/boost-1.41.0/image//usr" --layout=versioned threading=single,multi link=shared,static runtime-link=shared Note the failed filtering of --load-average=NN. bjam will idle around instead of building anything. Suppose it's trying to start zero concurrent jobs. Expected Results: As bjam seems to lack an equivalent for limiting the number of jobs by load average only, this should be mapped to a sane value like number of CPUs plus one.
