Well, my current version is squeeze :-)
Anyway, I looked into unstable and patched /usr/lib/libxmlsec1*.la
temporarily, which means clearing dependency_libs.
Unfortunately, this doesn't help. Libtool (ld) still links libgeier
against all the (unnecessary) libs as before. dpkg-shlibdeps warns about
and ldd libgeier.so outputs the same list as before.
So, clearing dependency_libs alone, doesn't help really, because the
additional libs are also introduced through pkg-config. Maybe it would
help, if libtool added something like "--as-needed" or similar to the
link command line. But I'm neither a libtool nor a ld expert.

Is there any dh_fixup_la_file debhelper or is it up to every single
maintainer to add some sed fiddling?
