It's somewhat irritating that linda doesn't say *which* library, but
that's beside the point.
One way to determine what the issue is by repeating the final link
line with -Wl,--as-needed to strip out unused libs. Then diff the
objdump output to see which libraries were removed and thus
extraneous.
However, please *test* the resulting binary. There are libraries out
there that don't declare all the libs they need and if you're using
one of those the result might be that you fix your package only to
reveal a bug in another. People building shared libraries can use
-Wl,--no-allow-shlib-undefined to detect this situation.
Hope this helps,
