Hello. I tried to run examples in Rubymacros, but I could not make it work. Could I get any help? sori-guyi-imac:~ ssor$ sudo gem install rubymacros Password: Bulk updating Gem source index for: [http://gems.rubyforge.org](http://gems.rubyforge.org) Successfully installed rubyforge-1.0.1 Successfully installed rake-0.8.3 Successfully installed hoe-1.8.2 Successfully installed sequence-0.2.0 Successfully installed rubylexer-0.7.2 Successfully installed redparse-0.8.0 Successfully installed rubymacros-0.1.1 7 gems installed Installing ri documentation for rubyforge-1.0.1… Installing ri documentation for rake-0.8.3… Installing ri documentation for hoe-1.8.2… Installing ri documentation for sequence-0.2.0… Installing ri documentation for rubylexer-0.7.2… Installing ri documentation for redparse-0.8.0… Installing ri documentation for rubymacros-0.1.1… RDoc failure in lib/macro.rb at or around line 57 column 24 Before reporting this, could you check that the file you’re documenting compiles cleanly–RDoc is not a full Ruby parser, and gets confused easily if fed invalid programs.
