Impossible to tell given the generalities you mentioned here. Personally,
I wouldn't have chosen to uninstall and reinstall Cygwin to try to fix
your original problem. I would have looked for what the problem was and
tried to fix that. It does sound like you had some clash in your tools
(ActiveState's perl and Cygwin's perhaps) but I can't be sure. One thing
I can say that you shouldn't do is install packages manually if you don't
know exactly what you're doing. 'setup.exe' is designed to handle all
the little details you wouldn't normally think of so using it is the
safest route. My WAG is that you had some Cygwin service or bash process
(or both) running when you uninstalled, which would leave those in place
and inhibit the installation of the reinstalled versions. Also note that
the Cygwin DLL comes from the cygwin package. It is not built on the fly.
HTH,
