It seems that libreoffice depends at the mere existance of libpaper.
I.e. I've got a system with libreoffice installed. The default paper
size was A4. (BTW I'm not sure why and how did I managed to do so
since it's Makefile does not check for paper size neither do use

Sometime later as a result of ports upgrading I've got print/libpaper
installed. And what do you think? The default paper size for libreoffice
(libreoffice itself was not touched by the ports upgading)
has changed!

Let me state that it was not so simple to detect the culprit and
fix it. BTW the (system wide) fix was to create a file
/usr/local/etc/papersize with a line "A4" in it.

So what if install a system wide default paper size while installing
print/libpaper? That may help both in gs case (when a binary is linked
with libpaper) and those that just use libpaper if it is installed.

I'd propose to leave a system wide default variable for a paper size.
I don't care if it is WITH_A4SIZE, DEFAULT_PAPERSIZE=A4 or else.

Yea, but those who will choose that non-default option and install
print/libpaper (in current state, i.e. without installing
/usr/local/etc/papersize file) will fall in trouble anyway.
