Comment 1 Stefano Crocco 2011-12-06 17:13:54 UTC

The problem here is that the function Init_prelude is hidden in ruby 1.9.3. I tried searching for an explanation for this change, but I couldn't find it. It seems that to allow compilation with ruby 1.9.3, the only solution is not to call Init_prelude. However, I'm not sure what this function does. The only hint I found with google is that it is used to setup the path for gems, but I don't know whether it is also needed for something else. However, here's a link to a thread in the ruby forum discussing a workaround for this: http://www.ruby-forum.com/topic/2323190
