ldd <program name> gives you the list of libraries a program you find slow
depends on;
dpkg -S <library> gives you the package from which belongs the library
pkg-revdeps <package> gives you the packages dependencies tree on which
a <package> depends.
pkg-deptree <package> gives you the packages tree of which packages depends
on <package>
Than I think that you need is
pkg-deptree <package> | depcount
where depcount is this file:
-----------8x--------------
#!/usr/bin/awk -f
/^ / { x++ }
/^[^ ]/ { if (pkg != "") { print x } ; \
printf "%s ", $0 ; x = 0 ; pkg = $0 }
END { print x }
-----------8x--------------
This not gives a perfect representation because pkg-deptree don't
repeat already list package. Exemple:
pkg-deptree libc5 xpm4.7 | depcount
will give:
libc5 27
xpm4.7 0
although xpm4.7 has has 4 packages dependencies on my system.
That because xpm4.7 depends himself from libc5 than all packages
who depends on xpm4.7 are allready list in libc5 and not reprint.
So, only put one package by run to get a correct list [it's a bit long
also].
BTW, pkg-* are in pkg-order.
