Note that calling gcc-config afterwards would recreate your original file again, so you do not really have to safe it. However, so far I had no problems. OTOH, I do not use a heavy C++ desktop and had already recompiled practically everything with 4.9

Now that 5.1 is in Portage (masked), you should keep in mind that emerging it will result in the 5.1 libraries being used, even if you keep 4.9 (or 4.8) as the default compiler. 4.8 for now. I was going to google and noodle around this issue, but since you brought it up This is not really guaranteed to work well. AFAIK, the only fully-supported configuration is having the latest emerged gcc version be the default compiler. It might still be best to install 5.1 locally outside of portage if you don't intent to make 5.1 the default system compiler. Naive question: Can't I use /usr/local/portage/. I guess not, nor my second 'dumb' idea to set it up as user 'portage' Ok so what is the overview how to install it (hopefully using standard gentoo methods) So that I can just use it for amd64 codes to test on test machines? Also, what about standard libs and custome libs -[1]? Later on I want to compile with it on arm64 in a cross compile environment for the arm64 target (Cortex A53).

You do know that both cephfs-0.94 and gcc-5.1.x have support for RDMA. It should really speed up some applications, particularly if you are running Apache:(spark|storm) or other in-memory codes on top of Apache-mesos (ebuild in BGO). The recently released (portage)t dev-java/sbt has gotten me much further along toward a working apache-spark ebuild, also in BGO. So things are rocking for low-latency, HPCC in gentoo. I only regret that somebody smarter than me is doing all of this. NONE of the old gentoo linux cluster devs are much interested in putting together a gentoo cluster from 100% sources; and I find that most baffling, particularly Donnie Berkholz. Many are using clusters at their work, based on other distros but little effort is being expended to bring 100% source solutions for clustering to gentoo. I do find lots of solutions for containers on remote (vendor) clouds and binaries for hadoop and such. Nothing so that the rank and file gentoo communities can build their High Performance Computer Clusters, (HPCC) from 100% sources. Strange, real strange, at least from where I sit THANKS for the help. James James
