Dear rrrBbert, the instructions are in fact for GNU Radio 3.8, so not for a previous version.
Anyway, I'd not recommend building GNU Radio from source, at all, when there's binary packages available. That's just way harder, and has no advantages. Especially, at high cost, avoid building on an embedded system like the RPi: these are not machines meant for building software. Developers who target embedded devices compile the software on their PCs and transfer the binaries to the embedded devices; in fact, building GNU Radio typically exceeds the RAM you have in an RPi by far, and the poor device, aside from compiling Megabytes of C++ code, also needs to start swapping RAM to the incredibly slow medium of SD cards. So, simply use Raspbian Testing on your Rpi, which simply comes with GNU Radio 3.8.1-rc1: sudo apt install gnuradio and done. There should be a guide how to update your Raspbian to that, somewhere (I'm not a Raspbian user myself, so I can't help you). That should be pretty straightforward, and at the very least, much, much easier than building GNU Radio from source. Also, a note on NOOBS/the raspbian, that it installs: Raspbian, for some reason, has decided that "all RPis are alike", which they really are not. The older RPi are least-performance 32 bit machines without acceleration for a lot of things, whereas the RPi 3 and RPi4 are 64 bit machines with support for accelerated vector math, which GNU Radio really uses *a lot*. So, Raspbian throws a lot of performance, as far as I know, by forcing software to run in legacy armhf mode. Sadly, "real" Debian (which Raspbian is based on) hasn't fully been ported to the RPi 4 yet, so I don't have a great alternative to updating your Raspbian from buster to testing yet.
