Depspec
Depspec is a small program written in Python that allows you to view a Binaries Dependencies (and symbols that it exports/imports from deps), currently it supports ELF (via marienz'es elf.py) and PE (via. diSlib64). also planned is UT package files (using the parser I wrote) and while it's not really a binary format gentoo ebuilds.
Downloads
You Can Download Depspec from the subversion repository [http://tfkyle.dyndns.org/svn/depspec/trunk/ here], it requires [http://python.org Python] (2.5+), [http://gtk.org Gtk+], [http://pygtk.org PyGtk], and [http://tfkyle.dyndns.org/svn/tfplib/trunk/ tfplib], currently it needs gtk, however in the future I intend to make a frontend using Qt atleast.
if you're using windows and don't have Python, Gtk, etc. there's an oldish standalone version [http://selene.tfkyle.dyndns.org/~kyle/Temp/depspec.rar here], just unrar and run depspec/depspec.exe
