I don't see there anything that we don't have.  I do see a lot of
stuff unrelated to building Emacs per se, something that just sounds
like personal preferences of whoever wrote that post.

I don't think we should be responsible for someone else's posts.  It
is better to maintain our instructions to be accurate and with all the
necessary details.

Please do tell if you find anything missing or incorrect, and we will
fix those deficiencies.

This is just the steep learning curve, something that each one of us
has to go through just once.  It is impossible to have all this
information in our installation instructions.
