The reason I'm reluctant to apply this kind of patch (although I did in this case) is I'm _going_ to break that environment again next time I change something. Either I'm afraid to make changes, or the environment full of random bugs I can't regression test bit-rots quickly. > > if [ -z "$SED" ] > > then > > - [ ! -z "$(which gsed 2>/dev/null)" ] && SED=gsed || SED=sed > > + [ ! -z "$(command -v gsed 2>/dev/null)" ] && SED=gsed || SED=sed > > fi > > Toybox provides a which this works with.

This is a clear host bug. *shrug* Applied anyway. I need to work out how to get toybox to build with more of toybox, which is always a chicken and egg problem...
