From: Charles Hoffman Date: 2008-02-08T09:00:01+09:00 Subject: rubygems.rb:87: uninitialized constant Gem::Mutex (NameError) Hi folks, I'm trying out code examples from Pickaxe 2nd ed. using the regular Ruby interpreter running on WinXP, and editing/running via RDT in Eclipse. Examples from the chapter on multithreading are giving me this error message -- though after displaying it, the program seems to run fine. Any thoughts on this? -- < Charles (Chuck) Hoffman > < http://nothinghappens.net >
