Indeed. So the reason that there is an issue at all is that man-db uses
libpipeline to run a pipeline of programs.
I've used Ludo's trick to see if could get more details:

I'm not sure this tells us much.
From libpipeline's documentation
(http://libpipeline.nongnu.org/libpipeline.3.html), it seems that libpipeline
accepts "program names", and it's unclear to me if it accepts full paths (would
be weird, but we never know).
If we can't figure it out, a workaround would be to wrap "man" to add
groff-minimal to PATH.
Thoughts?
