LGTM for the libpinyin part unless it breaks fcitx-libpinyin in a way I didn't know.

With a minor change, the updated ibus-libpinyin works.

You need to specify that this port needs its glib settings schema to be installed:
GLIB_SCHEMAS= com.github.libpinyin.ibus-libpinyin.gschema.xml

Otherwise, the engine crashes when you switch to this engine. I thought that it worked before, so I'm not sure what's the problem.

With this line, the corresponding line in pkg-plist can be removed.
