Installing orocos 2.5: rospack/rtt_typelib dependency

Hello,

I tried following the install instructions for the toolchain v2.5 at

http://www.orocos.org/wiki/orocos/toolchain/quick-start-linux

on a fresh debian wheezy amd64 install

the step: sh bootstrap.sh fails with the message:
----
checking out ocl

manifest /home/sagar/orocos-toolchain/ocl/manifest.xml of ocl from
orocos.toolchain lists 'rospack' as dependency, but it is neither a
normal package nor an osdeps package. osdeps reports: there is no osdeps
definition for rospack
----

So I tried installing from the .bz2 tarball. During that process, the
step: autoproj build failed with

---
autoproj: importing and loading selected packages

manifest /home/sagar/orocos-toolchain-2.5.0/orogen/manifest.xml of
orogen from orocos.toolchain lists 'rtt_typelib' as dependency, but it
is neither a normal package nor an osdeps package. osdeps reports: there
is no osdeps definition for rtt_typelib
---

Am I missing some step during the install?

Regards,
Sagar
