For Open/LibreOffice, OpenJDK I just omit "not found" ldd messages,
because those packages provide libs which are linked against other libs
located outside well known locations (probably specified
via /var/run/ld*.so.conf according to ldconfig(8)):
/usr/local/openjdk7/jre/lib/amd64/libzip.so:
libz.so.6 =3D> /lib/libz.so.6 (0x801608000)
libjava.so =3D> /usr/local/openjdk7/jre/lib/amd64/libjava.so

libc.so.7 =3D> /lib/libc.so.7 (0x80081e000)

libverify.so =3D> /usr/local/openjdk7/jre/lib/amd64/libverify.so
(0x801a46000) libjvm.so =3D> not found (0)
/usr/local/openjdk7/jre/lib/amd64/server/libjvm.so:

Setting LD_LIBRARY_PATH do the trick, but in my opinion you can ignore
that.

Accroding to rtld(1):
(...) On 64-bit architectures, the linker for 32-bit objects recognizes
all the environment variables listed below, but is being prefixed with
LD_32_
It's been quite a long time since I last used i386 binaries (except
those ran via linuxulator), but your /usr/local/bin32/wmc is compiled
against 32-bit libintl.so.9 and libiconv.so.3 (located
in /usr/local/lib32) and ldd probably see some architecture mismatch,
showing "not found (0)". You can always try to use truss(1) and check
what is going on, where all libraries are searched.
Maybe some developer can shed some light on this topic and explain us
how it's all organized :)
