It seems I should know a lot more to make gv running...

My only purpose is to view a postscript file content and as I know I should 
run gv, so i installed gv package and then in cygwin shell I type 
"/usr/X11R6/bin/gv.exe".

In the installation process there is nothing obvious wrong.

You mentioned I should run X first, what that mean? Is there some program I 
should run before I fire up gv?

Thanks.
