DISTUTILS_SINGLE_IMPL=1 is an optional var yes. I have elected to use it in conversions of old packages of this type. mgorny made it and I use it. Before I came across it I did conversions without it. Both work. Take you choice. It doesn't matter to me to use straight distutils-r1, however the point is that, without fail, these old ebuilds support only python2.7. Its use although arbitrary is totally apt.
