One additional data point: 

# cd /pkgsrc/pkgtools/digest
# make clean-depends clean
===> Cleaning for cwrappers-20220403
===> Cleaning for mktools-20220614
===> Cleaning for digest-20220214

The native make seems to handle the dependencies as I would have expected (and as bmake does without cross compiling), but the pkgsrc bmake clearly adds more.  The same is true for a not-unprivileged pkgsrc bootstrap.

By the way, the PATH includes the pkgsrc installed ${LOCALBASE}/bin:${LOCALBASE}/sbin prior to the normal path so that packages will be found.

I’m not sure whether cross-compiling would just work if I use make and not bmake, or if there is more to this.

Thanks for any help with this.

Cheers,
