The importance here is to have always the same package installed that
the user select.  The problem with dpkg-http was that it didn't select
the right package to upload compared with dpkg --print-avail [who used
the available files].

Then a user (like in my case) see gcc-2.7.3.4 selected (and may be
already installed) in the Select step, then, in the Install method,
see the 'want: gcc-2.8.1_i386.deb'.  This confusing a little, not?

The best solutions, compatible with dselect should be to always use
the available file to find the good version [I think this how dselect
work for getting the Available Version of Select]. If APT use another
scheme [as I think so], you should used the same scheme for the
download. The problem [if it is one] here is it possible to have
dselect and apt *not* have the same list of available package... May
be apt should always updated the available file correctly? OTOH,
changing method in dselect always need to run Update first.
