Are you by any chance using a virtualenv or something like that? It
looks like your app is using some compiled extension modules. I'm not
sure exactly where _lbfgsb.*.dll comes from--possibly Numpy or Scipy?
It's never been entirely clear to me exactly how rebase searches for
files, but I think by default it might only take into account DLLs
installed by Cygwin packages. So if you have some DLLs in a
virtualenv, for example, you have to manually include them. I'll
typically do something like:
$ find path/to/virtualenv -type f -name '*.dll' -print > dlls-to-rebase.txt
$ rebase -O -T dlls-to-rebase.txt
