Executive summary:

Just use the maemo 2.2/maemo 3.0 scratchbox install instructions, but
instead of installing maemo 2.2/3.0 rootstrap, just install the 2.0 
absolutely no reason whatsoever to keep the old scratchbox around.

Long version:

You guys need stop thinking dependencies and scratchbox versions are
black magic!!

1) The maemo 2.0 rootstrap should work just fine with latest scratchbox.

Why was the older scratchbox neccesary previously? Because at one point
of time only had right toolchain and patched dpkg to produce armel
.deb files. These features are now also present the lates 1.0 scratchbox.

2) shared library dependencies work just like in debian.

So, the version of library your package depends, is created from the 
file included in the -dev package. Now, since maemo 2.0 -> 2.2 includes only
bugfixes, there should be no new REAL incompatibilities. Which would consist
of adding, removing or modifiyng a exported symbol of the library. So if 
is a library package that bumps the version requirement in maemo 2.x, It's
probably a bug[2] and should be reported.

[1] they are in /var/lib/dpkg/info/*.shilbs
[2] most probably the library packaging brainlessly uses "dh_makeshlibs -V"
