Created attachment 368420 [details, diff] patch on current ebuild (remember to add local useflag) This has been added upstream, but is not enabled by default, so adding a new local useflag pacct seems appropriate. Tested on amd64 for some time - no issues. Patch is simple, but also new useflag is needed. <flag name='pacct'>Enable support for reading Process Accounting files (EXPERIMENTAL, Linux only)</flag> Committed in my overlay (https://github.com/thinrope/pkalin), commit details: https://github.com/thinrope/pkalin/commit/f8ad4cde65053c5f322d1f4bb15d74e15d382cfc
