Package: dpkg-dev
Version: 1.14.12
Severity: minor
dpkg-shlibdeps misses some symbols and thus prints warnings about not
using symbols from a library even when doing so.
When compiling xbuffy-3.3.bl.3.dfsg-5 I get the following warning:
| dpkg-shlibdeps: warning: debian/xbuffy/usr/bin/xbuffy shouldn't be
| linked with libXaw.so.7 (it uses none of its symbols).
but when I edit the binary to change the NEEDED section I get:
| $ ldd -r debian/xbuffy/usr/bin/xbuffy
| libYaw.so.7 => not found
| libXt.so.6 => /usr/lib/libXt.so.6 (0xf7eb8000)
| libX11.so.6 => /usr/lib/libX11.so.6 (0xf7db4000)
| libc.so.6 => /lib/libc.so.6 (0xf7c40000)
| libSM.so.6 => /usr/lib/libSM.so.6 (0xf7c28000)
| libICE.so.6 => /usr/lib/libICE.so.6 (0xf7c00000)
| libXau.so.6 => /usr/lib/libXau.so.6 (0xf7bec000)
| libXdmcp.so.6 => /usr/lib/libXdmcp.so.6 (0xf7bd8000)
| libdl.so.2 => /lib/libdl.so.2 (0xf7bc0000)
| /lib/ld-linux.so.2 (0xf7f2c000)
| undefined symbol: boxWidgetClass (debian/xbuffy/usr/bin/xbuffy)
| undefined symbol: commandWidgetClass (debian/xbuffy/usr/bin/xbuffy)
Thus those symbols are actually needed. (They are variables with the
object class of the widget, referencing the actual used methods as
function pointers, thus no other symbols from this library are used).

I'm missing a i386 unstable currently, but looking there at the binary
in etch, I think this will not be sparc specific at all.
