In particular if you are installing to a location other than /usr/local
you do need --prefix, and so have to run configure separately. (And
if you run pre-release or devel versions, you probably do want to install

What I would like the file to include is the information that you can
run without installing from the place you compiled, even after make clean.
That is a link of  /place/I/unpacked/bin/R to somewhere in your path
is all you need. And that does save disk space since during the install you
need two copies.  My installation procedure is

	./configure --prefix=...
	/place/I/unpacked/bin/R   # check it runs
	make clean
	make install

As pedantry:

on most (all) shells you will need to rehash, and in fact the default place
to install is not in the default path on Solaris (and I suspect most
non-gnu) systems.  But, would not a comment to read the R FAQ be useful?
