app-text/libwpd-0.6.6 merged. tested wpd2txt and wpd2html and these programs converted a .wpd file to respectively txt and html
Please also take look at Bug 39987. It's the ebuild for libwpd-0.7.1 version (newer) and it builds on amd_64 too. Besides that, AbiWord-2.0.4 says "libwpd-1 >= 0.7.0 required"
Done. ~amd64 added. When 0.7.1 gets added they should mark it as well.
