Yes, of course. I've now updated the instructions; there might have
been an extra reboot in there before.

Sigh, this one is a known issue, for over 7 years :(.
http://sources.zabbadoz.net/freebsd/lor/280.html
It is not reported in release builds at least.

Indeed. gmake has a reasonable-looking set of 5 dependencies, but git has 74.

Oh, sigh. The reason for this one is rather silly, and with luck it
will be fixed in a later package version.

It does seem that Clang asking to submit a bug report for EPIPE isn't
really desirable.

Anyhow, for my exploration I installed gsed and s/sed/gsed/ in
scripts/make.sh. We'd like to improve compatibility with GNU sed where
feasible though and I'll try to see what is being used here that we
don't implement.
