Hi
I had a similar problem. I eventually resorted to downloading the cygwin program from cygwin.com and it seemed to work. I think this had the libarary cygwin1.dll included. I'm still not sure what the problem was but I was just glad to be rid of that error message. There is probably a simpler solution and hopefully someone with far more technical knowledge than me can shed some light on this but I hope this gets you started in the right direction. I remember how frustrating that problem was.
