OK.

I think it cannot be made more optional than it currently is.
‘MAKEINFO’ is currently defined as:

  MAKEINFO = ${SHELL} …/build-aux/missing makeinfo

meaning that you get a warning when ‘makeinfo’ is missing.

Regardless, I would recommend the following to set up a development
environment for Guix:

  guix environment guix

I realize this wasn’t documented, so I’ve added it to “Building from
Git.”

Thanks,
