Additional context
problem is fixed by replacing oggenc and lame binaries with versions downloaded using apt install
prior to doing so oggenc would error when I'd run it ./oggenc: error while loading shared libraries: libFLAC.so.8: cannot open shared object file: No such file or directory
lame would work if i ran it from its directory, but would fail as part of the build citing the device missing libtinfo.so.5
