I use OpenOffice.org ports(japanese/openoffice).
Recently, l10N'ed helpfile is available for Japanese,
however, this port does not automatically install helpfile.
I made a slight change for both OOo ports.
However, according to http://www.openoffice.org/dev_docs/source/build_linux.html#BuildingLocalised
one should stop somewhere and extract helpcontent,
however, my experience(yes I know it is not a beautiful
solution), just extract before full build is ok.
I think this solution can be applied to other languages'
helpcontent(especially, japanese helpcontent has strange name, though ;-).
Fix: Two patches are necessary:
One is editors/openoffice
Next is japanese/openoffice
Over to maintainer.
Native language help pages are available since mid
august for freebsd openoffice port. Thanks.
