ldd /usr/lib/libqt-mt.so reports that it depends on libXft.so.1 and libfontconfig.so.1. As far as I can tell these aren't dependencies of libqt-mt.so itself, so they must be dependencies of one of the dynamic libraries it does directly depend on. Is there a tool that shows the dependency graph (not just the leaves as in ldd's case) for a given binary? Many thanks, Shaun
