Oh, wait.  That's not what I was looking for.  The addresses are ok, but
the paths *must* be the ones at the time the DLLs have been created,
because that's what ld uses when creating the image base addresses.  The
addresses combined with the installation paths don't make sense anymore.

Apart from that, since you seem to be installing the DLLs anyway, can't
you combine every crucial point during installation with a rebase?


Thanks,
