while you should be overriding -j# on `emake` lines, if you do want to tweak it via MAKEOPTS, you should be appending, not clobbering the variable broken code: sci-libs/libctl/libctl-2.2.ebuild:20: MAKEOPTS="-j1" emake || die # Note: emake gives strange errors. sci-libs/libctl/libctl-3.0.1.ebuild:20: MAKEOPTS="-j1" emake || die # Note: emake gives strange errors.
fixed.
