Could you explain the rational of removing them ?
AFAIK, the .la removal was not discussed, so starting by saying "we
remove them now because last time, we didn't discussed and it broke lots
of thing" is a little bit weird.

</I>><i> I don't think just building packages and removing the .la will work,

</I>><i> Reading these:

</I>><i> <A HREF="http://lists.debian.org/debian-devel/2009/08/msg00783.html">http://lists.debian.org/debian-devel/2009/08/msg00783.html</A>
</I>><i>
</I>><i> it looks like Debian are using sed to remove the .la files from
</I>><i> dependency_libs field in .la files, there's a debhelper script, IIUC
</I>><i> it's run before they build a package.
</I>><i>
</I>><i> This means it's something that a script run as root in the chroot can

</I>><i>
</I>><i> Meanwhile, just removing .la files will break a lot of builds (note
</I>><i> that we have a lot of packages to rebuild for e.g. new libnotify major
</I>><i> in Cauldron)... :(
</I>
Ie, we need to remove them in the proper order.
One first step would be to find the dependency tree ( should be
basically the same as BuildRequires ) and start bu shaving the leafs.
