Ok, this is a sticky problem.  The reason Redhat/Mandrake and
now we libtoolize many packages, is because with the default
libtool as used by most things have a bug, which I refer to
as the "relink" bug.  This is fixed by having a patched
version of libtool, and what libtoolize then basically do
is to install our patched version of libtool for the specific
package to user, thus fixing the bug.

A good example of the "relink" bug, is gdk-pixbuf.  If not
libtoolized, if build for the first time on a system, none
of the loaders in /usr/lib/gdk-pixbuf/loaders/ are installed.

Why this happens, are hard to explain, as I researched it
some time ago.  The basic principal, is that because we
build it with "--prefix=/usr", and then install into
"prefix=${D}/usr", libtool thinks it should relink some
of the components.  In the relinking, the "libdir" (defined
in the .la files) is defined as "/usr/lib...", and thus
the components/libraries do not get installed (if memory
serves).

Also, ${D} gets into .la files, and when the library of
that .la gets used, libtool tries to link in
${D}/usr/lib/libfoo.so instead of /usr/lib/libfoo.so like
it should.

This all is fixed in our version of libtool after much
research and testing.

Now what I propose, is that if we do not libtoolize Gnome2,
then we should at least write an eclass that patches all
"ltmain.sh" 's with the relink patch, and with our own
libtool-portage patch.

Anyhow, comments and suggestions appreciated.

NB: BCC me if you reply.
