mail/claws-mail docs fail to build

[tech-lists]

Hi,

context: 12-prerelease / ports r485597

mail/claws-mail docs fails to be built/installed and as there's no way
for the creation of the manual to be turned off, there is no way to
update the program.

[...]

gmake[6]: [Makefile:650: claws-mail-manual.pdf] Error 8 (ignored)
/bin/mkdir -p
'/buildports/usr/ports/mail/claws-mail/work/stage/usr/local/share/doc/claws-mail/manual/en'
install  -m 0644 ./claws-mail-manual.pdf
'/buildports/usr/ports/mail/claws-mail/work/stage/usr/local/share/doc/claws-mail/manual/en'
install: ./claws-mail-manual.pdf: No such file or directory
gmake[6]: *** [Makefile:460: install-manualdeDATA] Error 71

[...]

full failed build output is here:

do I need to make a PR in bugzilla?


thanks,
