Suppressing display of installation commands with @ is not very nice, since it makes it difficult to see what really failed. The problem is that install-bin and install-data assume that the install-start target has already completed, but do not have a Make dependency to enforce that. The 'ainstall' target that triggers install-bin and install-data does depend on install-start, so serial make happens to work. The fix for the reported failure is to make install-bin and install-data depend directly on install-start. I will attach a patch to the ebuild to do this.
Created attachment 203174 [details, diff] Patch to eggdrop-1.6.19.ebuild to add a sed call to fix the above issue, and to remove the -j1 on the install target With this patch, I can successfully run ebuild eggdrop-1.6.19.ebuild install with MAKEOPTS=-j.
