Jason is the maintainer, with a bit of Chuck's and my help.

I don't think that chmod +w is a good idea in general.  I don't like
to see tools fiddeling with permissions without asking.

We're working on a new release of rebase anyway.  This new release
checks for writability and prints just a warning without stopping
dead in its track:

  /usr/bin/foo.dll: skipped because not writable

That should be ok, shouldn't it?  Otherwise, what we can do is to open
the file with FILE_FLAG_BACKUP_SEMANTICS.  This would allow you to
rebase DLLs without write permissions if you have admin privileges.
