It says, after running ./configure:

    Finally, you have to invoke 'make check' [...]

This has the effect of running make [all], and then runs the test 
suite.

Ignore it at your peril.  At most, substitute a ‘lone make’ for 
‘make check’ if you're feeling lucky and have previously run the 
test suite.

Yep, *all* commands need to be run in the guix environment.  No 
need for ‘--ad-hoc make’ here as ‘make’ is already an input to 
guix.

Success!  \o/

You need to run this inside the environment as well.  You keep 
leaving it; that won't work.  It used to work sometimes, years 
ago.

Instead of tediously prefixing everything with ‘guix environment 
guix --’, just enter the environment once and stay there:

  $ guix environment guix
  $ ./bootstrap
  $ ./configure --localstatedir=/var
  $ make -j`nproc` check
  $ ./pre-inst-env guix build guile-fslib
  $ ...
  $ exit # or C-d, to leave it when finished

That's a rather standard way of doing things.  Does it work?

Kind regards,

T G-R
