I heard of toybox from working unsuccessfully with buildroot, ptxdist, openwrt, openadk, and possible semi-success with crosstool-ng.

But I never used toybox.  There is busybox, which I first met on Linux Slackware installation CDs.

I believe cvs is the most up-to-date way to keep up with pkgsrc tree, git would be some hours behind.

Git seems to have become the most popular way of maintaining and keeping up with source-code repositories.

NetBSD and OpenBSD both use cvs as their primary version-control.

Using NetBSD to cvs-update something on a Linux partition figures to be dubious, judging from my experience with "git pull", but FreeBSD seems more dependable.

I didn't know Gentoo make was gmake, haven't installed gentoo yet.  Does Gentoo have a plain "make"?

But I am aware that Linux is an anarchy of many different distros, so should not be surprised to see gmake in place of make.  Software developers who put "#!/bin/bash" in scripts seem unaware of this anarchy.
