For a guy who likes manually constructing pipelines, Ralph seems
inordinately disinterested in the intermediate stages when
troubleshooting.  ;-)

Unfortunately the PostScript output you've been sharing is not terribly
helpful; please hold off for now.  Your "nroff -man | cat -n" output is
the most telling clue we have so far, in my opinion.

Not likely--that's a shell script!

It might be worth comparing the /etc/groff/man.local files in both your
main distribution (which you haven't identified) and Alpine Linux.

I hear their diff command is a little anemic...

The groff_man(7) man page will tell you exactly where the man.local file
is installed.  View the man page and scroll down to the "Files" section.

I've never met anyone who had a grievance with netpbm before.  But it
shouldn't matter; if you don't care to use groff's HTML output support,
you don't need netpbm, and the build should not fail without it--but it
_will_ warn you (upon configuration) that HTML support will be absent.

[partial build log snipped]

I saw nothing remarkable or erroneous in that build log.
