"etc" is a standard extension which wraps Unix password database
related functions.  So it is not avairable on some platforms, e.g.,
mswin32.  WEBrick uses Etc::getgrnam to provide Utils::su (switch
user), which helps a user change process owner to non privilege user
after opening the privilege port 80 by privilege user.  This
roundabout procedure is a well known way to reduce security risk.  
But this procedure isn't necessary on non Unix platforms.  So you can
ignore absence of Etc.  WEBrick would rescues LoadError and would
defines Util::su as empty function instead if "etc" isn't available
indeed.

By the way, within the debug.rb, any errors are reported even if that
would be rescued by the target script.  Should some messages to relax
user be print?

Thanks,
