Building gettext on OpenBSD 6.3, I get this failure:
Updating man page gettext.1.in
/usr/bin/perl -w -- ../../../gettext-runtime/man/help2man
--include=../../../gettext-runtime/man/gettext.x ../src/gettext > gettext.1.in
Can't locate Locale/gettext.pm in @INC (you may need to install the
Locale::gettext module) (@INC contains:

/usr/local/libdata/perl5/site_perl /usr/libdata/perl5/amd64-openbsd

BEGIN failed--compilation aborted at ../../../gettext-runtime/man/help2man line
29.
*** Error 1 in gettext-runtime/man (Makefile:1660 'gettext.1.in')
This patch avoids the failure, leading to a message
"WARNING: The man page gettext.1.in cannot be updated yet."
- and the build continues.
