11 ## Transitional Hack ####
12 #
13 # RDoc was initially distributed independently, and installed
14 # itself into <prefix>/lib/ruby/site_ruby/<ver>/rdoc...
15 #
16 # Now that RDoc is part of the distribution, it's installed into
17 # <prefix>/lib/ruby/<ver>, which unfortunately appears later in the
18 # search path. This means that if you have previously installed RDoc,
19 # and then install from ruby-lang, you'll pick up the old one by
20 # default. This hack checks for the condition, and readjusts the
21 # search path if necessary.

26 It seems as if you have a previously-installed RDoc in

30 removing the directories:

41 p $:
42 $:.replace($:.partition {|path| /site_ruby/ !~ path}.flatten)
43 p $:
44 end
45
46 $:.each do |path|
47 if /site_ruby/ =~ path
48 rdoc_path = File.join(path, 'rdoc', 'rdoc.rb')
49 if File.exists?(rdoc_path)
