In RubyGems 1.3.1 this line is:

$ cat -n REL_1_3_1/lib/rubygems.rb | grep 274
    274	    @configuration ||= Gem::ConfigFile.new []

Likely this is the version you have (partially) installed.

Gem::ConfigFile.new has taken one argument all the way back to 1.3.1.   
I suspect you have a corrupted or edited install.  Please try removing  
RubyGems from /usr/local/lib/site_ruby/1.8 and reinstalling from the  
tarball.  You may need to remove RubyGems versions installed via  
package as well.
