Log Message:
Resurrect libreoffice4 from 2014-12-25 as libreoffice43, as found
in pkgsrc-2014Q4, with the adaptation to build with libcmis-0.5
instead of libcmis-0.4 to allow build with more modern pkgsrc.

This should bring back a version of libreoffice which is buildable
on netbsd-6 -- it certainly builds for me on NetBSD/i386 6.1.5.
