Changing the pin priority of of local repository of debs

[Charles de Miramon <cmiramon@nerim.net>]

Hello,
1) I've recompiled the kdelibs packages with other options and created debs. 
2) I put these debs in a /root/deb directory. 
3) I ran the dpkg-scanpackage to create the necessay files to make it an apt 
source.
4) I've added this new source on top of my /etc/apt/sources.list

The problem is that apt wants to update the locally compiled packages with the 
one of the old source. Both of these sources have a pin priority of 500. 

So I tried to raise the pin-priority of /root/deb but fiddling with 
etc/preferences was of no avail.

Finally, I found a workaround by lowering the pin priority of the original 
source by putting  in etc/apt/preferences

Package: *
Pin: origin download.uk.kde.org
Pin-Priority: 480

But it looks impossible to raise the priority of /root/deb because there is no 
'origin' label (I've appended to this message the result of apt-cache policy)

How do you create an 'origin' for the /root/deb repository ? 
His there any other way to tell /etc/apt/preferences/ to take into 
consideration the local repository ?

Cheers,
Charles
