Perhaps, I messed up the Makefile. Some time ago, I test-compiled lsp
on Rasbpian and CentOS and -lutil was missing. That got fixed in
meson.build but not in the Makefile I sent you. I'll attach a new
one -- this time as plain text ;-)

Oh yes, I didn't have the POSIX manual pages installed -- now, exit(1)
gets recognized as a reference. Thank you.

Yes, that was a typo. I'm on Gentoo and there is no libc-bin. But now
I have a direction to search. Thank you, again.

As I wrote: I (also) had novice users in mind when I implented the
Apropos pseudo-file (it can also be used for verification, that's
another use of it). I often watch novice users getting frustrated about
all the typing that is needed to get useful results. I know, first of
all, they need to train their "keyboard abilities" but some help here
and there could perhaps help to keep them on board or minimize
frustration...

Yes, one of the points where I thought pagers with additional
features could help...
