Qt installation issue on Maemo

Hi ppl,
I am trying to install Qt on maemo but it is failing to find the right qt package.
I have followed these instructions.
I added the following lines into /etc/apt/sources.list file on Scratchbox:

deb http://repository.maemo.org/extras/ diablo free non-free
deb-src http://repository.maemo.org/extras/ diablo free
deb http://repository.maemo.org/extras-devel/ diablo free non-free
deb-src http://repository.maemo.org/extras-devel/ diablo free

and then I ran the command from scratchbox
apt-get update
after which I tried
fakeroot apt-get install libqt4-core
but then it is giving error that
Couldn't find package libqt4-core.

Anyone has installed qt on maemo that can help me with this error??
I got these instructions from
http://wiki.forum.nokia.com/index.ph...h_Qt_for_maemo

Regards,
Yogesh

What does "apt-cache search qt" return?

apt-cache search qt
returns
kernel-source-diablo - Linux kernel sources for rx-34, rx-44 and rx-48 products
What does that mean??
If I searc for some default component like TCP or ssh then I get the whole list.
I guess my proxy is not working?? I am using VmWare Ubuntu dos it make any difference as to how proxy settings work??

It looks like your repositories do not contain Qt packages.
