It's been around for almost a year now I think (well over 6 months
atleast).

Get the genbuilddeps source and build it (the only real binary is the
libvfork, which wraps vfork so strace can follow it). It's not perfect,
but it's a good start. It will get *everything* used to build your
package, but because of dpkg-dev, it will always show perl. It also (as
someone pointed out) does not traverse the package list to reduce it
down. Also, on my system, since I use libnss-ldap, it picks up those
extra things (so be aware of it).
