It IS done at packaging time on XP, and tested on Win7
At install-time a rebaseall would be preferred, since we packagers do
not know how many dlls the client has installed, esp. those which might
clash.
perlrebase is mainly useful, if a full rebaseall is too large, and/or
another perl has to be rebased, which CAN conflict with the default perl.

Jason explictily listed TODO's in his rebase package README.
A setup database to skip already know addresses and rebase new ones into
the holes or at the end is TODO.
