Debes estar cerca, todo pinta bastante bien :)
Como cargas el fichero curso1.html en el navegador? como
file:///xxxxxxx/curso1.html o como http://localhost/curso1.html?
Si es con el primero entonces prueba con el segundo.
Animo.

> 1) Tengo instalado el ms4w en c:\ms4w
> 2) Ya instale el python 2.7 en mi pc, en c:\Python27
> 3) El archivo proxy.cgi modifique la primera linea con:
> Estaba: #!/usr/bin/env python
> ahora esta: #!C:/Python27/python.exe -u
> 4) Cuando en un browser indico: http://localhost/cgi-bin/proxy.cgi, sale
> la pagina de openalyers. al parecer ya esta bien el cgi.
> 5) Cree una carpeta c:\ms4w\apps\cursoopenlayers
> 6) Copie en un carpeta todas las librerias de openalyers en
> c:\ms4w\apps\openlayers\openlayers
> 7) Tengo el siguiente archivo curso1.html :
