## Extracts the dependent libary names from the named binary, @var{name}.
## If @var{root} is specified, the only libraries returned will have paths
## which begin with one of the cell-strings contained by @var{root}.
##
## The defaults for @var{root} are @code{@{"/opt/local/", "/sw/", "/usr/local/",
## "@@executable_path"@}}.  These root paths are intended to match all the
## relocatable libraries which should be included in an App bundle.  The first
## and second entries correspond to the MacPorts and Fink installation
## directories, respectively.
