Should the syslog extenstion be automatically installed if you use the
one-click installer?  Whenever I require 'syslog' i get the following
error:


C:\ruby\src\ruby-1.8.4_2006-04-14\ext\syslog>ruby test.rb
c:/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in
`gem_original_require': no such file to load -- syslog (LoadError)
        from
c:/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in
`require'
        from test.rb:13

I tried to run


C:\ruby\src\ruby-1.8.4_2006-04-14\ext\syslog>ruby extconf.rb

but got

checking for syslog.h... no
*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

How should I go about installing the syslog extension?
